This Stage 1 tuning file is engineered to awaken the sporty potential of the Seat Leon 1.4 TSI (CAXC engine), equipped with the Bosch MED17 ECU and software 513998. This calibration is designed to make the popular TSI engine more lively, responsive, and fun to drive.
Our remap focuses on sharpening throttle response for a more connected feel, optimizing boost pressure for a stronger mid-range pull, and adjusting ignition timing to extract more power. As an added feature, this tune also removes the factory top speed limiter (Vmax), allowing for unrestricted performance in a closed-course or track setting. It’s the perfect all-in-one upgrade for the enthusiast driver.
