Golf 5 1.4 TSI — MED9.5.10 380009 Bosch — Remap File
This Stage 1 tuning file is engineered for the innovative 1.4 TSI twin-charged (supercharger and turbocharger) engine found in the VW Golf 5, controlled by the Bosch MED9.5.10 ECU. This calibration is designed to significantly boost performance, targeting an impressive ~203 horsepower, and also removes the top speed limiter (Vmax).

Our remap optimizes the complex interaction between the supercharger for low-end response and the turbocharger for top-end power. By recalibrating the boost, fuel, and ignition maps, this tune delivers a much stronger, wider, and more linear powerband. The result is a Golf that feels incredibly responsive and pulls hard throughout the rev range, transforming it into a true performance hatchback.
