Leon Cupra 2.0 TFSI — MED9.1 386637 Bosch — Calibration File
This is a complete tuning package for the Seat Leon Cupra 2.0 TFSI, equipped with the Bosch MED9.1 ECU (software 386637). This package provides two distinct levels of performance, giving you the flexibility to choose the right tune for your car's hardware and your driving style.

The included Stage 1 tune is designed for a mechanically stock vehicle, delivering a significant increase in power and torque, sharper throttle response, and a more exciting overall driving experience for the street.

For the ultimate in performance, the package also contains a Stage 2 tune. This aggressive calibration is engineered for vehicles with supporting hardware modifications (such as a high-flow downpipe, upgraded intake, and intercooler) to extract the maximum possible power from the TFSI engine, perfect for track days and enthusiast driving.
