This is the third car I have had mapped by Celtic tuning and it's by far the best. The difference between stock and the modified vehicle is, in a word, outrageous. It's a completely different car.

I later had catless downpipes fitted and returned the car to Celtic for sensor deletion and another dyno run. Always happy with the service and advice offered, facilities are state of the art and you can watch your car on CCTV during the process.

I had my Z4 mapped yesterday and am very happy with the results. The car is much more responsive and the power and torque gains are amazing. The server was very good and professional.

Highly recommended.

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…
