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
Harry Yates
Had a gearbox remap on my T6 Volvo XC90. Shifts through the gears are now much smoother and I can def notice the difference in torque. Thanks folks.
Mr Christopher Mersom Volvo
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
