They build race trucks! They did a great job on my 2nd gen and they have a good group of guys working there. Totally recommend for anything small to a complete overhaul. You name it they do it. Thanks paul!

Great service and great people. Cant praise them enough.

I have been a diesel truck owner for 22yrs and have used a number of Performance shops over the years, some of which were great shops. That being said, despite having to ship my truck to Utah, I gotta say Paul and the guys at IDP far surpassed my expectations in all areas, communication, professionalism, customer service, advice on best direction to resolve the issues I was experiencing and the ability to squeeze me in in a reasonable time considering it was an emergency to get my truck back on the road asap. If you are having doubts about who to hire for your diesel service and performance needs, look no further than IDP, these guys get it done the right way!

When i bought my truck i bought i also got a warranty with it and they called the warranty company and got everything situated great place!!Definitely going to come back!!!

Good guys good work, they honor their warranty. I appreciate them a ton.

Paul and the crew here at IDP know what they’re doing! Truly! Best shop in Utah hands down. From every day maintenance and repairs to full blown race trucks they do it all. They work tirelessly to get the job done too. I’ve visited on late nights (10pm) where they are still grinding to get the job done! This is the only shop I will take my truck to, and it’s an hour and a half away from me! Can’t beat the service and knowledge these guys provide. And to top it off they only use the best parts in the industry to make sure the jobs done right!Paul once told me “I may not be the fastest on the block, but I provide the best quality I possibly can”. No corners cut, no BS run around when you are trying to obtain info. Doing it right the first time is the only option around there.Thank you guys for helping me along with my build. Nothing but great things to say about this place!!

Paul and his crew are awesome. Super happy with my trans. Highly recommend.

Fast, customer service oriented shop that exceeded my expectations!

Paul is not only an awesome guy to deal with, but he is honest and fair. He got my truck in very quick,diagnosed it and took the time to explain what was going on and in detail!He is a true master when it comes to his trade! I would recommend these guys all day every day without hesitation! Don’t waste your time going anywhere else!

Paul is a great guy and mechanic! He kept me in the loop every step of the way while working on my truck, and really went out of his way to make sure it was done right, and for an incredibly reasonable price. Can’t say enough good things about him and his work.

Paul is the best! Hes honest, does things right the first time, and has reasonable prices what more can you ask for.

Went in for an EFI live tune and ended up getting some transmission work done as well. He did a very thorough job as well as a quick turn around. Straight shooter, honest, and takes care of his customers. I would highly recommend him and will continue to go to him for other work on my truck in the future.

Great trust worthy people

Great shop at a great price. Paul went above and beyond to make sure I was satisfied with my duramax upgrades! Can’t wait to get some more work done!

Not only is Paul a good dude he also takes time to explain everything and is very thorough with his work. My vehicles won’t be going anywhere else from now on!

I called Paul after being recommended to Interstate Diesel by Starlite Diesel to have my Duramax tuned. Paul is super knowledgeable and was able to answer a lot of my questions. I am new to diesel tuning so there was plenty to learn. He was willing to answer questions even over the weekend which helped me a lot. I’ll take my truck to him anytime I need work done!

I had a check engine light go on my Duramax. Paid local dealership to repair turbo, worked for a few weeks and light came on again. This time the dealer said it needed a completely new turbo and quoted me $1000 more than they did weeks prior. Completely not trusting the stealership a friend referred me to Paul at Interstate Diesel and Auto. It was late evening and I figured I would leave a message, to my surprise Paul answered the phone. He actually asked me questions that other shops didn’t bother to. Such as what I use the truck for. I tow and don’t need a speed racer. Paul went over options for me and was very knowledgeable. He recommended what I needed instead of other shops recommending what they wanted to sell me. I know enough about mechanics to know there are many different turbos depending on your needs. After our evening discussion, Paul said he would go back to the shop and get me a estimate that night. He emailed estimate and time frame for repairs within a hour. The price was fair and he scheduled repairs immediately after parts arrived. My truck was done within days instead of weeks as other places quoted. I use my truck for work so time is money. Paul went out of his way for me and he will be the only place my truck goes for repairs. Nice to find someone you can trust that is a honest, fair, experienced mechanic, with great customer service. Highly recommend !

All the guys at Interstate Diesel Performance are great to work with.

Pauls a great guy. Honest and willing to help even if hes not the right guy for the job.

Has given me great service. Gets me in and gets me out. Honest guy to deal with.

Very reliable. Has the tools to get the job done right. Very few people do I trust with my truck and Interstate is definitely one of them.

Best and most honest mechanic around. I had my car looked at by another mechanic and didnt have a good experience there. Not with Interstste Deisel and auto. Had a great all around experience. Has very competitive pricing and he gets the job sone quick. Super nice guy as well. He keeps you up to date on what the status of your car/truck daily. I will be taking my cars to him from now on.

Paul is a solid dude and great to work with!

Best in customer satisfaction!!

Tunes are good
