This Stage 2 ECU tuning file for VW Golf 7 GTI 2.0 TSI (220PS) includes two versions: one calibrated for 98+ RON performance fuel and another optimized for lower-octane fuel. Based on Siemens SIMOS18 with software SC800LB700000, this remap delivers sharper throttle response, more boost, and faster mid-range acceleration. Ideal for both modified and export builds.
