Product Details
VF Engineering's Performance ECU Software unlocks a significant step up in power, torque, and throttle response for the Audi S4/S5/SQ5 (3.0T). 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 S4/S5/SQ5 so usable every day.
Each calibration is tailored to the Audi S4/S5/SQ5 (3.0T)'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 S4/S5/SQ5 that feels transformed the moment you press the throttle — backed by VF Engineering's decades of forced-induction and calibration expertise.
