This plug-and-play package unlocks dyno-proven horsepower and torque gains, sharper throttle response, and optimized drivability — all without sending in your ECU.

Dyno-Proven Performance Gains

Our engineers spent countless hours developing this calibration on the dyno and road. By refining spark and fuel curves, adjusting torque management, and modifying knock thresholds, we extracted reliable power increases across the curve. Expect stronger low-end torque, harder midrange pull, and more excitement at wide-open throttle.
