Description
Upgrade your BMW X3 M or X4 M with the CarBahn Performance 751 HP Stage 2 ECU Software Power Package, engineered specifically for the S58-powered F97 and F98 platforms. This performance package combines CarBahn ECU software with a high-performance heat exchanger and CarBahn high-flow air filters to deliver substantial gains in horsepower and torque while maintaining the factory safety systems.
On 93-octane fuel, the Stage 2 calibration produces up to 728 HP and 658 lb-ft of flywheel torque. With 100-octane fuel, output increases to an impressive 751 HP and 677 lb-ft of flywheel torque. The CarBahn EVO Intelligent software continuously adapts to different fuel octane levels, optimizing performance while retaining existing engine safety features and adding additional protection when necessary.
The software was developed with the CarBahn heat exchanger installed to achieve the claimed power output. The heat exchanger is also required for CarBahn's matching factory warranty.
