Product Details
VF Engineering's Performance ECU Software unlocks a significant step up in power, torque, and throttle response for the Audi RS5 (2.9TT). Developed in-house by VF Engineering's calibration team, this precision engine tune sharpens acceleration and drivability across the rev range while keeping the factory smoothness and reliability that make the RS5 so usable every day.
Each calibration is tailored to the Audi RS5 (2.9TT)'s engine and integrates seamlessly with the factory ECU, so you keep OEM refinement, cold-start behavior, and safety systems intact. The result is a stronger, more responsive RS5 that feels transformed the moment you press the throttle — backed by VF Engineering's decades of forced-induction and calibration expertise.
