I received all my parts within 2 days. Thank you so much for that. I did not request second day but it was a great surprise. So far the install is working great. ATP has proven time and time again to be a top notch company. I wont shop anywhere else for my Duramax parts.

Rob, ATP, and co. ,
When Mike Porcaro answered the phone at ATP when I first decided that after endless hours of scouring the forums, picking the minds of reputable members, going through the arduous task of dissecting all the good information from the bullshit, little did I know that I would walk away from my first experience with ATP beyond satisfied, but also gain someone that I can honestly call a friend.

You don't find that level of honest, insightful, and agenda free service these days. There's nothing wrong with promoting products you truly believe in, but it becomes blatantly apparent when someone is there just to empty your pocket. My experience with Mike from my first phone call is what had me requesting him, and only him to continue to assist me with my account.
That's not to say that the other employees and sales reps at ATP aren't of the highest quality.

I'm just someone who knows when and if you're lucky enough to find a person like Mike, a person who treated my truck like it was his own, who patiently, professionally, and courteously dealt with all the hesitant & reluctant thoughts that myself, and I'm sure most of us who are truly passionate about this life have....well that was apparent from the time I was merely a potential client he may never hear from again, to the time I handed over my credit card number and told him I truly trusted him with my hard earned money.

I never once had an uneasy feeling or second thought throughout this 3 week process, and that was due to the fact that I was updated and informed consistently, and most importantly, honestly. I never had to reach out and inquire to where things were, because my inbox or voicemail already had a message from Mike to ease my mind. If a product was back ordered, he didn't tell me it was out for shipping. The respect and appreciation I have for that type of sincerity is endless.

Most representatives know how to regurgitate the label of a product. It's easy to tell the difference between those and the ones that have lived and breathed this shit for years and have an internal database that extends beyond the phone, into the garage, and out into real world application.
THOSE are the guys I want guiding my decisions, and THAT is exactly what I got from Mike P. He handled my account from day 1, to the day I'm writing this email. An email that was something I willingly offered as it was the very least I could do to show my appreciation for both him, and ATP Trucks.

My parts are in the mail. The transaction is complete and I could walk away without taking the time to write this. But I'd be doing a great disservice if I was to not commend Mike Pocaro for being a great representative of ATP, a great representative of Diesel Performance, and more importantly just a good man who was true to his word, a man who left me a more educated person in this field, and someone I will not only be happy to build a truck with, but a damn good friendship as I continue my business with this outfit. Thank you Mike.

Hey guys. I just wanted to give a huge thanks to Mr. Mike Porcaro for all the awesome support he gave me throughout everything. He was super helpful, patient, and just absolutely outstanding to go out of his way to see that I was taken care of completely. I have never used ATP Trucks before, till I started helping a co-worker with his 2005 LLY, and I have never been helped so much by any customer service group. I have been in the diesel performance game since about 2007, and not a single company or person has helped and walked me through things as well as Mike. I greatly appreciate all that you guys have done for my co-worker and I. The truck has never ran better!

Hello rob, I would like to tell you what a phenomenal job you did with the new tune I finally got the truck out and loaded on. The turbo braking is great and the turbo responds very quick with next to not smoke. Two thumbs up very pleased with the tunes and thanks again for all the time and patience answering all our questions.

It was our pleasure you guys continuously go above and beyond anytime we need answers or have a problem. We have run into problems with things before that we have contacted the manufacturer of an item and cannot get answers from them. You guys are always ready to help no matter what the problem or who we talk to, you should be very proud of your business and your staff. You guys have a business ethic that is very rare to find anymore. What is really great is you guys are not just selling parts you use what you sell and have a real interest in the business you are in. Again I thank you for your time and patience you and your staff have shown us and I wish we were a little closer but one day we will meet in person.

Hey Ryan,
I talked to you today about issues on getting the switch for my efi live to read. Your tech wasnt available but you said you would have him call me and within 5 min he gave me a call. I don't remember his name, Cody? Anyway I just wanted to applaud you guys on your customer service and even though the problem was on my side everyone I spoke to was very helpful. The problem was that I did not get the ground wire seated enough but the 5th time was the charm. LoL. I recommended you guys to a friend also he is getting ready to buy efilive for his lmm

I just wanted to drop you a note and thank you and ATP for all of your assistance with my project. Just about everything I've done recently with my truck involved a lot of "first time" work. ATP's commitment to customer service and quality products lives up to the hype that I've read in countless discussion forums.

So far, so good with the truck after the custom tunes were dropped in...very happy with the results to say the least.

Thanks again and take care,

Everything installed great! Just finished a 600 mile trip last night towing our 18k toyhauler and the heavy tow tune is spot on. We gained 2-3 MPG from the previous tunes I had and the power is insanely smooth and the EGT's we're way more manageable than before. I can't express enough how happy I am with the tune package.

After hearing tuning wouldn't be the culprit I looked closer under the hood. Looks like the wires going to the sensor ripped out. I have no idea how it happened or how it didn't throw a code until I did the tuning, but I can see the sensor and where the wires should connect. Should be an easy fix.

Took out a 2014 vette at a light this weekend. Loving the tunes. I'm amazed how clean it burns, even on max effort.

Thanks for getting back to me. i talked to calob a couple days ago and he told me it was on the v2 and he also sent the tune to me.

Thanks for the heads up on my truck not being stock. I had a bully dog programmer and then an edge programmer that i thought were taken off but maybe there were some changes. I have you tunes on there now and it seems to run great.

My dad (Jim L...) was the guy that came in last week or so ago and camped out while you guys did some work to his truck. He had really nice things to say about you and your team there at ATP. He said it was nice of you to let him camp out in the conference room and was glad that you guys stayed late to finish his truck so he could make it to Alaska in time. I was glad to hear this because i referred him to you and he is not one to have other people work on his stuff. he is DIY kinda guy but he had a good experience with you guys.

thank you for the great products and service. i will be purchasing more stuff soon.

Yes the new switch is installed along with the tunes and everything is great. It was a pleasure working with you and the staff at ATP trough this whole ordeal. The mix up with the switch was taken care of quickly and when i had issues installing the tunes into the truck Monte and Cody I believe were the guys that I talked to were a major help. My calls were answered ever time I called and I was helped and walked through the process until we figured out that my tunes were done on the pre-release from EFI Live so even though the program was saying it had the latest update it didnt and once the guys showed me were to retreive the pre-release from everything went as it was suppossed to from there. This was the third set of tunes that I have gotten from you guys and if I ever need any more or any parts that you guys carry I will diffently be using you guys again. A big thanks from me to ATP's intire staff for a great business and even better customer service.

By the way- love the way it runs now. Very little smoke in performance but from a roll will burn tires first, second, and chirp third. Max effort is borderline stupid- feather throttle through first and second, and hard spin into third. Smoke on max effort, but that's completely understandable. Also, no more 3-4 shift flare at WOT. And no rattle from over-fuel if I stab the throttle.

Thanks again for everything!

I just wanted to take the time to write back and say, "thanks." The tunes work great, low smoke on all but the hottest tune, and I am quite confident that once I swap in a lower-mileage turbo even that slight haze will clear up great. I am making over 20 pounds of boost under throttle, and I am very happy with your work. Thank you for all you do and keep turning out a great product.

I really appreciate your help and everyone else at ATPtrucks for answering all of my questions(probably to many at times) and providing excellent service! This is my first diesel truck so it is all relatively new to me but working with you guys has made all the difference. I still have yet to install my blocker plate and tie rod stiffeners but that will be going on today! The Efi live with the downpipe and exhaust is like a whole new truck. I will be in contact again shortly when I order the Edge Insight CTS. Again, it really has been a great experience doing business with you. Enjoy your weekend!

If I can keep my right foot out of it, I can get great mileage on the DD - 90 tune, and still get where I'm going without an issue. The tow tunes are awesome with the turbo braking around the Coast Mountains in BC. Cuts down on the white knuckle driving and I arrive more relaxed.

I know you guys probably get this a lot but I had my efi live installed yesterday and I couldn't be any happier how it sounds and runs! Very pleased with your work!

Brian – 12/4/13

Thank you very much! By far the best customer service of anywhere.

11/26/13 – Curtis

I wanted to say the work you guys are doing is amazing.  A group of us are running the tunes from you guys and we love them. I bought a truck with efi live and can't wait to get the tunes and replace my terrible backyard ones.

Long story short we love your tuning and are heavily promoting it to our friends with diesels, and there are a LOT of them. Thanks!

11/5/13 – Joe

Rob I cannot say enough about your tunes. There are 8 subcontractors with the company I get most of my loads from. We all hand calculate our mpg. There are 4 one tons (all dodge but mine) and 4 1/2 or 3/4 tons. We compare mpg and maintenance costs monthly and discuss mods etc at a monthly BBQ. My truck with your tunes out performs them ALL!

Now I've owned big rigs and a small company before, most of the guys have not so I know how to care for equipment but the versatility your tunes offer are a HUGE reason my numbers are so stable. Be it 300 lbs or 4000lbs in my bed I've got the tune to match!

Thanks a million for your tunes!

10/16/13 – Joe

First off. I love the way my truck runs with your tunes.  A well running truck is mandatory to feeding my family. I drive about 3000 miles most weeks.  I deliver oil field/commercial AC parts etc. I had another tuner before that promised mileage gains but didn't deliver.

I hand calculate EVERY tank, which is usually one a day, and with your tunes my mpg bumped just under 2 mpg!  Actually amazing!  More than that it runs smoothly and doesn't smoke.  I cannot thank you enough for what y'all did to my truck.

I have been at this a while and never assumed tuning could produce the results I needed.  I'm thinking of adding 3 more trucks next summer and every one will have your tunes.

Thanks for what y'all did for my business.

10/16/13 – David

Right On!!! Thank you very much. You guys have been a huge help with truck and anytime I get the chance I recommend your tuning options.

10/7/13 - Ryan

Thanks! By the way I love the tune. I got almost 21mpg from kennewick to boise with a 6inch lift and 35's. Really impressed.

10/2/13 – David

Thank you guys for everything, I couldn't have asked for better customer service.

9/28/13 – Renato

I already knew u guys were the best at this but I just wanted to thank you for the tuning! I could not be happier! I will definitely be getting more tunes from u guys in the future! Thank you!!!

9/23/13 – Dylan

Awesome!  Top notch service!

9/7/13 – Jason

I just wanna say thank you for the great service and great product. I received the AutoCal yesterday and installed it immediately. Very pleased with the ease of installation and quality of the product and tunes. I had a (competitor tune) since the truck was new, and the drivability of your tunes blow it away. I wont bash their product because it has worked fine since I bought it. My daily driver tune with them was Level 3 160hp. They daily driver tune you guys built is only 100hp but the truck feels so much more powerful because of the increased throttle response even with a lower power tune. Thank you again, and when the truck changes and I need new tunes (lift pump, manifolds/up pipes, and transmission) I will be coming back to ATP.

9/4/13 – Gus

As always you guys have it shipped and expected arrival in awesome time. Keep up the good work, everyone at ATP is always a pleasure to deal with. I will continue to purchase as much as possible from your company just due to the amazing service and prices you provide.

9/3/13 – Jesse

Thank you for the great fast service I can't wait to try out your tunes!

8/26/13 – KC

Oh mike! Great job with the tune, I didn't load the newer tune I kept the other one, but got a 1st place pull leaving second in 55 feet behind!

8/22/13 – Mike

I finally got all my gauges installed, and I am more impressed than ever with my truck and your tune.  I mounted my probe pre-turbo between #5 and 6.  WOT only breaks barely 1000* if you hold into it for till about 90.  Very impressive for how responsive the truck is and having a pretty decent amount of power.  I set the cruise control at 90 on a Montana back-road on a cool evening and it was pretty steady at about 850*.  I cannot believe how cold the truck runs.

My last couple of trips to Boise and have been in right in the 19MPG range @80mph.  I have barely broken 20MPG at 80MPH on a few tanks in favorable conditions.  Thanks again!

8/19/13 – Jonathan

Exellent! Thank you so much! Golden star for everyone at ATP!

8/20/13 – Darrell

Hey guys, just got back from a camping trip towing a 11,000 pound 5th wheel.  I want you to know I used the 20 HP and the 50 HP tunes quite extensively.  Please pass on to Rob that the 50HP tune was exceptional during our trip around the Cabot Trail. There were three climbs of 13% grades that were over 4 miles long.  The truck worked like a beast.  My exhaust temps (using the DPF input probe temp) only rose over 800F once  - and only at the end of the climb.  Thanks again guys - your assistance in getting me up to speed was outstanding - Rob's tunes worked like magic!!!!!

No no…thank you guys.  It’s not to hard doing business with the best diesel perf. guys around!

To The Owner or Manager,

The reason for this email is to thank you and your staff. My name is (customer name) and last week I purchased your dsp5 tuning for my 2006 duramax.

The experience with your company was great after calling many times over the last couple months with a lot of questions about what I should do and talking to everyone on your staff I think all I can say is thank you. Everyone was willing to take the time and explain everything, they were very nice and helpful. As a small business owner myself I can appreciate how great of a group of people that you have. No one wanted to make me wait to talk with the person that I started with they were all willing to help just like the last it has been the best customer service I have ever had. By the way the tunes make amazing power and hopefully the fuel mileage will come as well.

Thank you again and have a great weekend


I had a great experience purchasing the clutch from you, and am glad I chose ATP over (competitor). Mike was great to work with, and the clutch was delivered on time, just like he said it would be. I have already recommended your business to several diesel truck enthusiasts, and I look forward to doing more business with you in the future

It's simply amazing what you guys do the truck runs awesome! You have a great staff there btw, very patient and helpful.  Thanks again I am a ATP/Tuning by Rob fan forever!


It's been a pleasure doing business with your company and I will be sure to pass along my recommendations.


The tune is awesome. I love it. It makes life a lot easier when a bolt on product actually bolts up without any problems. Thanks again for the great service.



The tuning was excellent. The truck works very well.



The tuning is great, and super clean.  I couldn't be happier, thanks for all the help.



It's going great, the customer really likes it, he is still wanting more power so I will be talking to y'all soon about a retune. Thanks for the follow up.



Thanks man I appreciate it!! You guys are top notch!!



AWESOME!  More than happy with it.  A return customer for sure, and thanks for the great customer service.



Thanks for the follow up. The exhaust has been working out great so far!  Easy to install and sounds good. Next is a DSP5 from you guys.



Its going great... love the power...



The tuning is awesome!



You guys are awesome thank you!!!



Tunes and new turbo are running great. Thanks again for the great tuning in the timely service.



I finally got the efi live in the truck and got the exhaust on and I could not be happier the truck runs amazing! It's like a totally different truck.



Thank you what a great product!  You guys did a good job.  My truck runs really well!  Great fuel mileage also.



Thanks for the awesome customer service.



So far so good. Getting 18.8 mileage on average which is awesome.



Worked great! Thanks


We have got everything installed and everything works great! You guys are awesome. You guys keep up the good work you have a customer for life.



Thanks for the follow up, my truck is running great with the efi live that y'all recommended, I should have done this earlier.



Yeah it's working great, like the power on the 100hp setting.



Thanks for checking in, I love the tunes it is night and day between (competitor) and Robs



It's awesome man.  Brought my mileage up from 10mpg to 16.5. Haven't tried any hotter tunes than economy due to not having my pyro installed yet. Thanks for helping me out!!



Also I wanted to say I am very pleased and have recommended you guys to several fellow dmax owners . Thanks again! Customer service has been excellent!



The tunes weren't for me they were for a buddies lbz. I'm pretty sure he likes the s#$t out of it to be completely honest with you!



Autocal is working great I love it. I made a second purchse for a Transgo Jr, and tie rod sleeves.



I appreciate y'all checkin up on me! I love the autocal! Haven't really hammered on her too much yet, I want to set up my gauge pillar first. Overall I am very happy with it BUT the only complaint...I lost my beer coozie hahaha
Thanks fellas! Take it easy!



I couldn't be more happier with the Autocal and the tunes that came with it. Great work and service!! Got the truck on the dyno and made 410hp 718ft lbs torque on stock tranny and no lift pump (lb7) pretty awesome! Thanks again guys!



It all worked great! Tunes are great too. Thanks so much! You guys do great work!!!



Again your product and team have come through and continue to provide a consistent level of customer service that many companies should take note of.



All is good. After 5 quick phone calls, the fun has started. Truck runs great! !  !   Can't wait to line with the guy at work with the (alternate tuning product).



Working great,will need new rear tires soon.  Thanks for checking.



Thanks again Rob, that's why I always recommend you, I can always get ahold of someone there! Not to mention tuning is bada$$!



I finally got a chance to install the turbo and tuning yesterday and I can say that everything is working out great! There is a much better "feel" to the truck and everything seems to be working together nicely thanks to Rob's tunes. Thanks for the follow up and I look forward to doing more business with you guys in the near future.




The lockup box is working great. My only complaint is that my buddies like to hit the lockup button randomly and it pisses me off!



(Joe Customer) and I purchased the V2 together and we love it.  We played around with it while waiting on custom tunes from you and it is nothing short of amazing.  We are going to install the custom tunes into my truck tonight.  I will let you know how it goes.  Thanks for checking back with us.  It shows that you guys are committed to customer satisfaction and that is getting hard to find these days.  We really appreciate it.



Fantastic, passed smog on friday and registered the truck on Monday.   Also I'm averaging about 20 mpg around town.



The AutoCal is working AWESOME!!! Robs tuning is freaking good! You guys have the best customer service i have ever dealt with. Thanks again for helping me get it set up and get working. I will recommend you guys to anyone needing something in the diesel truck industry.




I love the tuning. My truck does too. We towed the 13.k 5er last week and it was so much better than stock and or the (competitor). thanks so much. will let all my dmax friends know about you guys.



My autocal is great, i love it!



I love it! The tunes I got from Rob are great! Dustin was also very helpful with ordering them and answering my questions. It's a completely different truck now. I didn't think I would ever contemplate building my tranny but now I can't wait to. But that's a little down the road from now!



My products arrived today.  Thanks so much for your help, friendly service and timely delivery.  I can't wait to get it all set up.  Please tell Rob and Dustin how much I appreciate their help.



Just wanted to say thanks for all the help you and everyone at ATP gave me on the tune for my LMM.  Wow!  I now have a brand new truck that is unbelievable.  You guys have a great product and excellent support.  I could not be more pleased with the performance and the MPG.  I have already experienced over a 20% MPG gain around town.  You may have turned me into a "tuner"!  More mods may be on the horizon.  I cant believe the difference!  If you need a testimonial, please feel free to use this or let me know where to post it.  I am very excited about my truck now.  Thanks again.
