Description

Stage 1 consists of an individual reprogramming of the engine management system of the vehicle, whereby engine parameters such as ignition, injection, throttle response, and torque limiters are recalibrated for safe, daily-use performance on premium pump fuel.

Stage 2 is a custom-adjusted calibration where all relevant engine parameter values are further optimized to accommodate additional mechanical modifications such as aftermarket sports exhaust, headers (catless and high-flow catted applications), and upgraded cold air intake systems.

All calibrations are developed for the best possible performance and results within safe operating margins and to retain excellent drivability.
100% emissions compliant (with compliant hardware installed).
