Really great guy friendly and professional will definitely always bring my business here he helped me through a difficult time with my truck and wouldn’t rec anyone else
I've been around automotive my whole life working in shops and dealerships, grew up on a junkyard, raced and built hot rods, and I have to say that Corey is extraordinary. What a guy. He is the best. I hope he stays in the business and passes on his brilliance. If your diesel is ill, this is the shop to go to. He fixed my truck when nobody could help me. I rate him 10 stars out of 5. Keep up the great work Corey.
Cory is the best diesel mechanic I’ve dealt with hands down. Didn’t know him from Adam and I called in a serious bind, he made time to get me in and got me back on the road asap. Very knowledgeable guy, and he’s great at explaining what’s wrong and what will fix it. He even kept me updated as he made progress because the issue wasn’t as simple as we’d hoped. Any questions I had he got back to me quickly and never seemed bothered that I had more questions on top of previous. This is the only place my trucks will go from now on.
Gave them a call asking a question about a 6.0 power stroke he helped me immensely told me I needed to swap out the ficm and that solved my issue 10/10 recommend!
I've had work done and called and talked at great length with these guys and they've gone out of their way to answer my questions and help me with diagnosing my vehicles. Great people and great service. I wouldn't count on anyone else
Definitely a good diesel mechanic, and a decent turn around time for getting rigs in and out. He has experience with various engines and knows whats best for your specific application. Whether its for towing, horsepower, just a daily driver, or a weekend warrior.
Corey is super knowledgeable and knows any diesel truck in and out. I wouldn’t take my truck anywhere else. He was able to figure out an ongoing issue I was having for months and got me back on the road in a timely manner.
Cory went above and beyond on my father in laws 2004 F350 6.0 powerstroke and he is extremely pleased with the outcome! After spending thousands with another performance shop that that did a poor job on the bullet proofing. I referred him to Cory who I know for a fact is extremely thorough when it comes to these engines. He could tell you just about anything when it comes to 6.0’s. The truck runs phenomenal and Cory took the time to properly explain the process to Tracy and kept him updated from start to finish. Cory even showed us where the flaw was from the other shops machining in the o ring heads. I’m confident when I say diesel performance earned a customer for life from my father in law.
Corey is one good guy to have around for your diesel trucks i called him one day about a problem with my truck not starting when it got warm he told me it happens alot and gave me a recommendation to start with standpipes and dummy plugs so I got them changed and the truck runs amazing has all its power back if your having trouble with your diesel engine give Corey at diesel performance and he will get your truck running better then ever
Absolutely the best around not just a specialist on one platform equally versed on all three, goes above and beyond for any paying customer. Definitely the only place I will go for any diesel related business!!
Great people to work with. had an issue with a power stroke and gave him a call, he helped me over the phone to get it running. highly recommend them to anyone and everyone
If you're looking for a friendly, professional, and honest Diesel tech...then Diesel Performance LLC is for you! My son's truck started acting up and took it to my local mechanic shop they had it for a day and had their "diesel expert" look at it. They said they couldn't find anything wrong so they just cleared the code. We picked the truck up and drove it home, and the check engine light came back on. I was very frustrated and started looking around and came across Diesel Performance LLC. Corey listened to me about what the truck was doing and right away he started telling me what he thought it is and he said bring it down. Corey found the issue just like he said it was a bad injector he also found a very small fuel leak informed me of it and was able to fix it right away. Diesel Performance LLC is where I will take any diesel issue, I have in the future. Corey and his wife are what I call "Good People"...very honest and very helpful.
Cory has fixed both of my trucks a few times now from engine work, transmission work and even small leaks everything is always handled in a timely and honest manner great place to take your truck to
Diesel Performance is the best shop around the greater Morgantown area for any diesel work. Corey knows his stuff and takes his time to do the job right. I couldn’t have been happier with how my 6.0 powerstroke turned out. It’s running better than ever! Would highly recommend!
Great people, great work, Cory is very meticulous when it comes to his diesels he takes a lot of pride in his work and will make sure the job gets done right the first time!!!
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!
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.
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.
Excellent work on my 2015f350 , kept me up to date during repairs and even suggested things I could do myself to prolong engine life. 100% recommendation to anyone needing diesel work done. Thanks guys!
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!!!
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!
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.
Had a Chevy duramax work truck giving me problems was loosing money and probably clients all at the same time took it to 3 different shops problem kept coming back. 7 months ago Corey fixed it and not a problem since I owe you big time thanks for the outstanding work . He got it done when he said it would be done and he promised me he would get to the bottom of the issue and that he did thanks again
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! ✊🏿😍
