Description
Unlock refined performance gains for your BMW N74-powered vehicle with the MG Flasher Stage 1 OTS Tune. Designed specifically for vehicles running stock engine hardware, this calibration safely maximizes power output, throttle response, and overall drivability while maintaining smooth and reliable operation across the entire RPM range.
Stage 1 software is engineered for drivers who want enhanced performance without requiring hardware modifications. The calibration optimizes boost pressure, ignition timing, torque delivery, and fueling to eliminate factory powerband dips and improve consistency throughout acceleration.
A valid MG Flasher Flasher License is required in order to flash any OTS or Custom Map.
