After several hours research I found Celtic tuning offered the most. The car has a very smooth power delivery and have noticed a reasonable gain in MPG. I still can't believe how fast the car picks up; the Torque has increased so much I need to carry an extra of pants! This remap is by far the best I’ve experienced and would never hesitate to use again.

HAVE AN AUTOMATIC?

Alongside the engine control unit (ECU) we are also able to provide transmission control unit (TCU) software to help further enhance your vehicle. There is a lot of limitation built into modern gearbox software to help hold back the power gains you are trying to achieve from your engine, our gearbox software overcomes this and helps transform the way the car drives. Some of the modifications include raising maximum torque limiters, faster gear shift speeds, increased clamping pressures to prevent clutch wear, increased engine RPM limiters and much more…
