I had my BMW 135i 3.0 litre Twin Turbo Re-mapped by Celtic tuning on 8th April 09. Although the job took longer than expected the results are amazing. The car was running 306 BHP pre install, the next day I put the car on the rolling road at Well Lane Turbo Centre. At first the figures were disappointing 163 BHP???, The car was spinning up on the rollers so after some sticky tyre stuff and 2 people sat in the boot!!!! we got a reading of 365 BHP (59 BHP over standard), the operator said he had never seen such a smooth power curve, (Corner 2 corner) and was truly amazed at the results.  I was sceptical at first as most of the reviews I had read were for either Diesel cars or naturally aspirated. I can only say thanks to Luke and the team at Celtic Tuning, Great Job, I would recommend to all.

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…
