Unlock the full potential of your 2009-2017 BMW 550i with the GCA Performance ECU Tune, engineered to deliver significantly more power, sharper throttle response, and a more engaging driving experience.
Designed specifically for the F07, F10, and F11 BMW 550i equipped with the 4.4L Twin Turbo V8, our custom ECU calibration optimizes boost, ignition timing, fueling, and torque management to maximize performance while maintaining smooth drivability.
The result is immediate throttle response, stronger mid-range acceleration, increased top-end power, and a noticeably more responsive vehicle throughout the entire RPM range. Whether you're driving on the street or enjoying spirited weekend drives, the GCA Performance tune transforms the way your 550i performs.
Our tuning software securely saves your factory ECU file before programming, allowing you to restore the vehicle to its original factory calibration at any time.
