Description
Unlock refined performance gains for your BMW S58-powered vehicle with the MG Flasher Stage 1 OTS Tune. Designed for vehicles running stock engine hardware, this calibration safely maximizes horsepower, torque, throttle response, and overall drivability while maintaining smooth and consistent power delivery across the entire RPM range.
Stage 1 software is engineered for drivers who want significant performance improvements without requiring hardware modifications. The calibration optimizes boost pressure, ignition timing, torque delivery, and fueling to eliminate factory powerband inconsistencies and deliver a more responsive driving experience.
A valid MG Flasher Flasher License is required in order to flash any OTS or Custom Map.
