What People Say About Us

For my wife and I, our truck is another member of our family. You cannot separate us from our 'BigBadWolf' and just like any special member of our family we want nothing but the best for it's care. It is very hard to find a mechanic that we can trust. My wife came across Supreme Diesel Performance and decided to give them a try based on the excellent reviews they have received so far. It took no time to realize that the reviews so far we're on point. We were very impressed by the knowledge that they have in diesel motors and the professionalism and integrity the crew had throughout the process of getting our truck back on the rode. More specifically showing me the issues and the steps taken to ensure we would not have any further problems down the road. What's more, they squeezed us in their tight schedule knowing that we were on our way up North for a long road trip. There was no doubt in our minds that there passion in life is diesel performance. We have a 2012 6.7L power stroke and I could not imagine going anywhere else to keep my truck running for another 150k miles. Nick and Vic were very personable and spent time with the both of us addressing any questions we had. Overall, they treated us and our truck like a family member and I felt confident in their abilities. I wanted to leave this review to explain that these guys are serious about what they do. And If i need anything done, it is worth the commute from Cocoa Beach to get the best service I've had in over 5 years.

This is the best family owned diesel shop I have been in. They repaired the DEF system on my 2013 ram 2500. They set a very reasonable price and stuck with it... would not take a penny more even though they did more than anticipated. We were on the road and stranded and treated like best of friends or next door neighbors. Wishing all the best for your business

"Nick and his team at Supreme Diesel Performance are extremely knowledgeable , thorough and efficient. I purchased my first Diesel Truck a few weeks ago, a 2008 Ford F-250 6.4L... and took it up to SDP to schedule a inspection. Nick took a few minutes to give a quick inspection and let me know a few items I could work out while waiting for my detailed comb through appointment that I was able to schedule. I told him he was like a diesel whisperer the way he was in tune with the truck... so much knowledge and experience.. I knew I found the mechanic for anything that will arise on my new truck...So I took my list and got to work. I have used them for regular maintenance items (oil change and fuel filter) They keep me informed about potential problems and recommended maintenance and repairs. If you are anywhere within the Jacksonville or northeast Florida area and need a diesel mechanic.... take the trip to SDP, you will be in great hands with The Diesel Whisperer and his amazing team for any diesel truck for service."

The crew at Supreme Diesel are top notch. They truly put their customer's first and do everything they can to make sure you are taken care of. I needed my truck back on the road for a work trip, Nick and his tech (sorry forgot his name) made sure it happened for me. This is the only shop I will take my Duramax to. They are very knowledgeable and straightforward. Thank you Nick and the rest of the Supreme Diesel team! Appreciate all y'all do!

I was traveling through Jacksonville florida when my truck gave me the power reduced sign. These guys fixed the problem and gave me a peice of mind. I will only use this shop in Jacksonville they are honest and have empathy for what you are experiencing, if you're having trouble with your diesel you would be a fool to use some other shop!
