Description
Unlock maximum performance potential from your BMW N74-powered vehicle with the MG Flasher Stage 2 OTS Tune. This high-performance calibration is designed for vehicles equipped with a High Flow Downpipe or High Flow Catalytic Converter, delivering significant gains in horsepower, torque, and throttle response.
Stage 2 software is engineered for enthusiasts seeking the highest level of performance from the N74 platform. It optimizes boost pressure, ignition timing, fuel delivery, and torque management to ensure strong, consistent power delivery across the entire RPM range while eliminating factory powerband limitations.
A valid MG Flasher Flasher License is required in order to flash any OTS or Custom Map.
Important: This calibration must be used only with a High Flow Downpipe or High Flow Catalytic Converter.
