What customers say

Warm welcome , coffee on tap whilst you wait, had a auto gearbox remap , on my 2006 Volvo xc70 se lux AWD , although the some issues with the gearbox prior to the map , it did eliminate them to a degree , but I have done a gear box flush all is good…

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
