I had just had my 2003 Audi S4 remapped, what can I say easy if you have an S4 get it done. I noticed a difference straight away pulls much more in every gear and did a test before the remap - 60/100 mph in 5th gear 12.5 sec after it was 10 sec flat.

Now that's a big difference in any language and so much smoother as well.

The guys are very easy to talk to going to take my diesel jeep down next 10/10.

Cheers guys

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…
