customer Audi
Tuned my D36 420i to stage 1 ECU remap and Gearbox XHP stage 3 remap. Happy miles, can’t stop smiling. Very responsive Highly recommend JFAutomotives. I’ve been with them since 2020 when I had my mk3 Skoda fabia 1.2 Monte Carlo edition. Had induction kit and BOV for that car. - April 2024

Took my Golf GTI for a DSG gearbox service and was greeted by a helpful receptionist who answered a few questions. Staff were very polite. Very happy with the work done. 👍
