Description
Take your BMW N63-powered vehicle to the next level with the MG Flasher Stage 2 OTS Tune. Designed specifically for vehicles equipped with a High Flow Downpipe or High Flow Catalytic Converter, this performance calibration delivers substantial increases in horsepower, torque, throttle response, and overall driving excitement.
Stage 2 software is engineered for enthusiasts seeking maximum performance from their N63 platform while maintaining smooth drivability and refined power delivery. The calibration optimizes boost pressure, ignition timing, fuel delivery, and torque management to provide consistent power gains throughout the entire RPM range without the dips commonly found in factory calibrations.
A valid MG Flasher Flasher License is required to flash any OTS or Custom Map.
Transmission tuning is strongly recommended for optimal performance and drivability.
