Second time back now to JFA automotive Kent 1st time for an engine & gearbox map absolutely changed the car it is now amazing! Second time was for a dyno on the drag car, friendly staff good equipment free coffee what more do you want definitely recommend
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
Arrived 8.30 Saturday morning, a technician armed with laptop tuned the gearbox,so now the truck changes earlier keeping the revs lower,I was a bit hesitate about having it done,but it's definitely better with no problems.
