About Us

Gwatney Performance Innovation can perform nearly every performance modification imaginable to a wide variety of vehicles. Custom ground camshafts have become a mainstay at GPI - especially for the LSx motor platform. We often venture into Supercharged and Nitrous projects - and bring the total package together with a custom tune using our own in-house DYNO. 

We offer several packages as mentioned in the video above - and often a good place to start is with bolt-ons. Headers, Airbox modifications and custom tuning will set a foundation in your performance car for anything you would like to do next. 

We really prefer to have a face-to-face consultation with our performance customers -and it all starts by contacting us here!

We are a unique company offering performance upgrades and custom tuning for a wide variety of modern and vintage performance vehicles. We handle everything from custom ground cams to LS swaps - and utilize our own in-house DYNO to bring every single parameter of your car to peak performance, 

Corvettes, Camaros, Mustangs to Ferraris - we literally work on them all, even though we are based out of a Chevrolet dealership (Gwatney Chevrolet) in Jacksonville, Arkansas. We are on the cutting edge with our custom ground camshafts - and we have literally one of the best on-staff tuners in the nation.
