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

These guys really know their stuff. I went there for a TCU gearbox upgrade which has made all the difference on my car, they were really competitively priced and helped advise me on a few other bits as well. I’m definitely going back there again for some more upgrades. I highly recommend these guys, not…

Great job tuning our BMW and Touareg! Had both engine and gearbox stage 1 done on both. The gearbox tune made a big difference i must say! Good booking process and efficient with time. Highly recommended!
