Absolutely blown away by the Stage 1 map by Celtic Tuning. Beautifully smoothed out under comfort driving and at a flick of a switch turns into a torque monster that pulls hard and fast! Outstanding performance! Looking forward to replacing the tyres and breaks every week 😉

Had my 2014 530d mapped and the results are mind blowing. Car was already quick but now it’s a whole different car, great fast and efficient service.

Would 100% recommend

I have used Celtic Tuning twice now once for a Mercedes c250 and more recently for my new BMW M6, massive performance gains with a fast friendly and professional service.

Highly recommended!!

AUTOMATIC

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…
