SCT Performance

SCT unlocks greater vehicle performance through ECU calibration, so your vehicle is better equipped to meet your specific needs. We've released performance calibrations for hundreds of vehicle makes and models from Ford, GM and Dodge. Our calibrations are quickly and easily uploaded to the vehicles engine control module using our handheld programmer technology. By optimizing vehicle calibrations, SCT tuning unlocks greater vehicle horsepower, torque and drivability. SCT aims to provide top-shelf performance when and where its needed most, and to continue as the benchmark for aftermarket tuning solutions.

As a result of its recent merger under Derive Systems, SCT, Bully Dog, Bully Dog Big Rig, and Derive Efficiency brands have integrated into a world-class operation and a dominant force in the automotive technology space.
