Will not call back; was interested in scheduling dyno tune. Called and no-one ever picked up. Left numerous messages over the course of a week and still no response.Update: Finally was able to reach through FB messenger.

Excellent Service when it comes to Dyno Tuning.

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.

Mr Dempsey, the owner of Evolution, is absolutely awesome. I highly recommend if you own a Corvette that this is the place you need to come to. He has the know-how and the facility to complete any project on your new or old Corvette. Im sure he could tune or fix probably anything that you brought to him. what I really appreciate is the honesty of this shop they are good people kind of a southern hospitality type of place. You will not go wrong coming here highly recommended I would give more than five stars if I could.

Hands down the most knowledgeable, non-judge mental, and experienced speed/tuning shop I have ever known. Dempsey dialed in my C5z on a street tune, explaining the process, the car every step of the way. During the drive he identified a sound that was a product of my garage header install last weekend. He is a perfectionist that wanted to fix it before I left his shop because he cares about the longevity of every vette he touches - even though the issue was my cause. Sounds sappy, but I felt like I left as a friend not a customer. Look no further, drive from far, this is your guy.

Mr Dempsey did an excellent job tuning my 1998 c5 Corvette. They are good people with a great shop. They have the know how. Highly recommended. I will be using them in the future.

Couldnt have been happier. If you drive a performance car (especially a GM) this is the place to go for dyno or tune work. Dempsey is a wealth of knowledge and super friendly. Did a CTS V and a LT5 DOHC C4 ZR1 for us. Hard for a car guy to leave his baby at a shop, but I have no fear leaving anything at Evolution. 🏁🏁👌

Dempsey is a top notch mechanic. Not only does he work on high performance vehicles but everyday drivers. He is honest. He is the only one I will let touch my Vette. And I can promise you, I am VERY picky and have OCD with my car. He is understanding and very patient with me.

Awesome shop. Dempsey and Mike do great work and are great guys. Got a lot of work done on my 95 6 speed. Got engine upgrades in my future. If you have a vette that needs works or you want some awesome mods these are the guys.

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.

94 Corvette convertible was overheating and just not running well. Mike and Dempsey took care of it and at a fair price. They came highly recommended by a fellow Corvette owner and I see why. They are the Corvette guys!

I bought my 91ZR-1 to Dempsey last November to complete what he refers to as the Dragon heart package....I already had headers and top end porting to my Z....Even though it took longer than expected ( problems with the cam grinds) I opted for cams to go along with everything else),I picked up my car last Saturday...I live in NY and took amtrak out to fredricksburgh...Dempsey was good enough to pick me up at the station and take me to the shop....I have to say when I saw my car I was impressed....Dempsey had the entire car detailed using Adams products and it looked great....Even powder coated the motor a nice silver with red lettering ...Came out sharp..I spent basically the next two days in Virginia ripping around on the roads out there 66W,81N,plenty of back roads and even skyline drive......Car performed great no issues....448 to the wheels with 403 torque..So,even though there were some issues along the way, hey it happens,Evolution motors delivered a good product.....Not many mechanics on the east coast that specialize in the ZR-1 platform...Dempsey is someone you can sit down with and discuss where you want to go with your build....👍👍John....

Very helpful and knowledgeable of the question did I ask

Terrible service on both occasions I bought my ZR-1 here. Bolts improperly torqued or not tightened at all, transmission oil leaked out, many items neglected. Owner prefers to joyride cars instead of fixing them.Steer clear of this place....phillip ryerson...the unfortunate DEER damage wasnt the primary reason for my returning visit. I really wish I could have enjoyed the same level of service as you received.

A super qualified staff that provides great service!

Dempsey and his crew are great, they do awesome work and are very friendly

Do not bring your LT1 here

Simply stated Dempsey is the best!
