Talked to Corey, the man takes PRIDE in his work. I bought a 2016 Durmax he did work on several years ago no issues solid truck. Still providing me with answers to questions everything I need to know. If she ever needs work I'm talking to Corey or having them do the work on it.

They did a great job diagnosing the problem with my 21 Ram 2500. They were quick and very informative about the parts needed to fix it. Best service I have ever received! Will definitely be using them for all my repair needs.

Honesty goes a long way and Cory is very honest and helpful. There is no need for a diagnostic computer when it comes to Cory. HE KNOWS HIS STUFF. He can repair for you or give you advice and what to do. 10/10

Text Cory from the side of the road while he was having dinner and took time to reply and tell me exactly what my 6.0 was doing. Offered to drive out and give it a look. Told me the most common symptoms. Very knowledgeable!

Diesel Performance was hired multiple times from my employer that specializes in engine testing for emissions on light, medium, and heavy duty diesel engines. The work was always done without any short cuts, which was important for us. Our engines needed the OEM intended parts and installs for proper data collection. It never seemed to matter the make or model engine, Diesel Performance always knew their way around it without question.After seeing their work tested, I was comfortable enough to use them for my 89 W350 that I was having trouble with. Upgraded turbo, full head rebuild, KDP fix, tuned injection pump, and a clutch upgrade. I also saved me a lot of time searching on the internet for what I wanted and how to make it happen by talking to Cory. I told him what I would like out of the truck and he gave me exactly what I wanted. No issues with my 33 year old truck since then and it's been something I'm comfortable daily driving 6 hours to see family for the holidays with more power than I need.Can't thank the guys at Diesel Performance enough!

Cory is a great guy. I was traveling through West Virginia and the truck started running hot. I called the dealerships office in the area and no one was able to get me in. I called Diesel Performance and Cory realized I was from out of town and agreed to stop what he was doing to give me a diagnostic and possibly fix it. I towed the truck there and in less than 10 mins Cory was under truck looking for a leak. This man was incredible! He taught me a lot about diesel engines and how they work in just a few minutes of testing the radiator system. He charged me a fair price for the diagnostic and I will be leaving my vehicle with him to fix.

This guy is one of the best diesel technicians around. He's so good, I take my truck to him from almost 3 hours away from my home . Don't hesitate to call him for any diesel needs. He'll give you awesome advice and service. And they treat you like a friend not just a customer. Two thumbs up. Thanks Diesel Performance!!!

I inherited my pap s old dodge and didn t know anything about it but wanted to clean it up and make sure it was 100% Cory knew exactly what this truck s common issues were and went over the entire truck quick! I never thought this truck would run like this, but wow. Multiple times now I ve imagined pap shaking his head at how this thing screams. I m always hitting Cory up asking him about random stuff. Guy is a gifted engine builder for sure.

Corey, Lindsey, and the other mechanic (didn't catch his name) were super professional, fast, and knowledgeable! They had my freightliner back on the road almost as soon as I finished unloading. I also felt inspired by watching Corey make calls to promote his business(es) while he was waiting for my payment to go through. A breath of fresh air to see young people doing big things! Diesel Performance, you guys are amazing, keep up the well above average work!

Very friendly people. The garage isn't impressive but the workmanship is worth it. We used this place for a few different jobs on our truck. The team seems to know there trucks. Sometimes there is a wait to get the work done but when it's finished it done right. Finding it is the trick. It's in a crazy local. They are in the progress of moving into a bigger garage on a local rt. This is a great small business in the process of growing bigger. Great guys great work.
