How the Remap Calculator Works

Pick your vehicle type, make, model and engine, and the calculator shows the standard power and torque for that engine alongside the figures for each stage. They show what a standard engine in good health typically gains, and your own car's result depends on its condition, which is why it goes on our dyno before and after.

The figures are a starting point, because every map we write is custom. A qualified motorsport engineer writes it in-house for your car, which our car remapping page explains in full.

Press Book Your Remap and your vehicle and the stage you picked come straight to us, and we'll get back to you to arrange a day.

Have to say I had an incredible experience with JTK.. emailed them and got all their suggestions for what I should do with my Golf GTI as I have no idea John was very helpful and booked me in and everything went smoothly on the day and the job took the time they said it would. Couldn’t recommend them enough and the receptionist lady was very helpful and friendly sorry forgot her name.

So I got a hybrid turbo from muchboost installed in my Mercedes c220 and was advised to get a custom remap on a dyno so I contacted John got it booked in and he also offered hydro clean as an option and It was worth every penny I couldn’t believe the difference it made plenty of power and ticking over like a dream thanks again
