Description

Stage 1 consists of an individual reprogramming of the engine management system of the vehicle, whereby the adjustment of the engine parameters (e.g. ignition, injection, throttle response, torque limiters, etc.) is calibrated 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 systems, headers (catless and high-flow catted applications), and upgraded cold air intake systems.

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