Description
Unlock up to 729 HP from your BMW F9X X3M or X4M with the CarBahn Performance Stage 1 ECU Software. Designed for both Base and Competition models, this ECU calibration is engineered to increase horsepower and torque while maintaining the vehicle's factory safety systems and adding additional protection where needed.
The CarBahn EVO Intelligent software continuously adapts to various fuel octane levels, allowing the calibration to optimize performance without compromising safety. The Stage 1 software also removes the factory top-speed governor.
Authorized CarBahn dealer installation is required.
