The Active Autowerke BMW Software Tuning Collection consists of specifically calibrated software for your BMW DME. We take careful control of the factory control unit and modify the maps to increase horsepower and torque safely and reliably. The end result is a vehicle that drives as smooth as the OEM calibration, but with increased throttle response, power, and torque. On turbocharged vehicles we also control the air fuel ratio to make sure that it is safe at increased boost levels!
