This Stage 1 tuning file is precisely engineered for the modern Seat Leon 1.4 TSI with the CZCA engine, managed by the Bosch MED17.5.25 ECU. This calibration is designed to enhance the driving pleasure by making the responsive TSI engine even more engaging and lively.

Our remap focuses on improving throttle response for a more direct connection between the driver and the car.
