"I've been going to Dempsey (Air Force veteran) for more than 7 years. He and his team (Daniel and Julian) are the only ones I'll trust, not only with my 4 Corvettes, but with my daily drivers, as well. His automotive knowledge (in particular of the Corvette) is amazing and extensive. He's fair, transparent, and trustworthy. He and his crew are masters of their craft. If there is ever a problem with any of his work, he works to make sure it's resolved. Thanks for taking good care of my cars over these years. Aim High … Fly-Fight-Win!"

"In my opinion don't take your LT1 here. I brought my car back multiple times for the same issue. The problem was never fixed. Another big name shop was able to properly diagnose my issue and fix my car within a week. Edit: Dempsey, claiming my review is fake is comical but its a good conversation starter at car meets. I have my invoice and credit card charge to prove I'm real. I should have sent my car to Pray Performance from the start. Good luck with everything EX CEO of Syndicate of Speed."

"I was very pleased with the work done to my car here. Dempsey is a great tuner and was able to fix all the problems my car was having and got me 428rwhp at the same time. These guys know all about these cars and was able to guide my build with their years of knowledge. I will be returning here with all my corvette business. (Update went back for a full build and got overcharged by about 3k. My fault I should have paid better attention. Also the dyno numbers are incorrect I did cnc’ed heads cam full intake and exhaust and made around 450 which after spending 13k made me ask questions only being around 20 hp over cold air and full exhaust but the car was faster so I let it go. Just go to Mike at elite speed and performance. He actually did the work on my car just not the tuning and made good suggestions on things to do. I ended up getting it retuned by Landon who works with him and the car made 486 on a dyno jet and ran better since it was having some drivability issues. Both Mike and Landon know what they are doing and will take good care of you.)"

"Go see Dempsey, he knows Corvettes, inside and out, they do it all. I don't trust anyone else with my C7 and it's going back for more upgrades/Tuning in Spring. Thanks Dempsey & Team!!!"

"This is the only shop I would trust with my Corvette. Dempsey is an expert in his field and an absolute professional. He is the kind of guy who can walk up to a running car and tell you what is going on with the motor before he even pops the hood. He tuned my Z06 when no other shop on the east coast was able to and managed to squeak out almost 800HP with just headers, exhaust and a pulley kit. No matter what improvements you are seeking for your Corvette, he can easily make your dreams a reality. I recommend Evolution without hesitation."
