What customers say

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

I got a stage 1 tune for a Golf R, engine and gearbox. This is our family car so it was about tightening up the response and adding low-end torque to improve driveability. I turned up, the job was done while I waited (less than an hour). They had free coffee and good wifi so…

Amazing difference on my VW Touareg after having the Gearbox Mapping done, to compliment the engine Map i had done. These guys are always efficient and know their stuff!. Highly recommended!
