Custom Performance Tuning

Custom Performance Tuning (CPT) is an ECU tuning company located in Spartanburg, SC. We specialize in the Subaru, Ford and Mazda aftermarket performance, with more to come later. We pair our tuning with performance parts from Custom Performance Engineering, Long Tube Headers and some of the other top aftermarket parts manufacturers. Our tuning focus relies on some of the best software engineers such as COBB Tuning, HP Tuners, Diablosport and other open sourced software. With over a decade of experience in racing and tuning, we incorporate that knowledge into every build we are a part of. A history of building high performance vehicles yields a wealth of know-how to get the power you need out of yours. A library of builds showcases customer projects as well as our own motorsports events.
