The new 3.0 Twin turbo engine fitted to the 335d & 535d variants is a truly impressive feat of engineering. With two inline turbos it provides unstoppable performance from very low rpm?s. The smaller turbo is used for quick boosting off the mark up to 3000rpm at which point the larger turbo takes over to provide top end torque thus eradicating the lag which is evident on all large turbo engines. The power once remapped by ourselves is truly impressive and really needs to be experience to be believed. We remove the 155mph speed limiter for those wishing to test the genuine 170mph+ capabilities. We develop all of our software on the rolling road to ensure accuracy in terms of both power delivery and also to ensure fueling, boost pressures and exhaust gas temperatures are all within tolerance. Our aim is for maximum power whilst maintaining optimum reliability.

STAGE NOTES

Please note the torque figures differences are due to the nature of the Automatic gearbox and the kick down. The BHP figures are correct but the torque is higher than claimed.

WOW, I knew the performance would be better but was totally blown away by the difference. Absolutely effortless performance with devastating mid-range overtaking ability!! Everyone shopping around for a re-map should look no further than Celtic.

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…
