BMW X5 M ECU Flash

Mase Engineering

Our custom BMW X5 M ECU Flash has been proven to make a substantial increase in horsepower and torque over stock. By recalibrating fuel/ignition/boost tables we were able to extract an additional 37 Max HP and 83 Max TQ. Drivability will be much improved with a better throttle response and a smoother delivery of power throughout the whole RPM band. We highly recommend this flash for anyone looking to bring out the full potential of their car.
