What changes

Shifts that keep up with the engine

A remap adds torque. If the gearbox is left standard, its own torque limit can cut that back, and the shifts stay set up for a standard car.

  • Shift response up to 20% quicker, with less clutch slip under full load
  • Paddle reaction up to 40% quicker in S mode
  • Raised torque limiters, so your engine tune is not clipped
  • Higher red line and launch control where the gearbox allows
  • An optimised shift pattern

Written in house, tested on our dyno

Our own file writers calibrate the gearbox for your car and the engine tune it runs, then we test it on our Mustang 4WD rolling road.

Questions

Common questions

Will it shorten the life of my gearbox?

No. We tune within the tolerances of your gearbox and engine. We do not over-tune for big numbers.

Can it be put back to standard?

Yes, free of charge if you bring the car back to us, for example before a lease car goes back.

What if a main dealer update wipes it?

Bring the car back and we will write it again free of charge. It is part of our lifetime software support.

Is there a money-back guarantee?

Yes, 30 days on Stage 1 engine tuning and gearbox tuning. We put the car back to standard and refund the tune.

Do I need to tell my insurer?

Yes. You should tell your insurer about any modification. Many do not charge more, but not telling them can void your policy.
