Well worth the wait! On the first booking there were floods in the town, so it had to be cancelled (Kevin tried to get through and made it to within ½ a mile of the house but was turned around by police!). On the second booking Kevin was held up with another job and traffic, but I was kept updated throughout the day. The car was causing some problems at first but Kev worked around and got it done within 1 hour. Took it for a short test drive (due to myself having limited time) and at first the difference wasn’t massive – it certainly pulled better through the gears, and I was told it would get better as I drove it more. I think it was a combination of the road I drove it on, and over expectations (having been in a M3 the day before didn’t help!). Â That evening when I took it out I could really test it, and it certainly had made a difference! I had the opportunity to test it against a newer 525d and I consistently pulled away from it. Acceleration in every gear could be felt, and hard acceleration in 1st and 2nd gear caused everything to fly to the back of the car! It has made driving the car so much fun. Motorways – up to speed very quickly and no problem picking up in 6th gear from 50mph (previously I’d have to drop it into 5th or even 4th), cruises with ease. A roads – no problem overtaking in 3rd, 4th or 5th gear (previously it was hard to know whether to drop it a gear, and it didn’t make as much progress as it should have). B roads – now so much fun for a big car. The whole driving experience is much improved thanks to the remap, and the throttle response is so much better – a slight movement of the right foot can be felt, whether you are ¼ or ¾ throttle. It’s faster than a 525d and Focus ST, and isn’t embarrassed by an M3 when making progress through traffic. Car had covered 82k miles at the time of remap, and it has been 2 and half months since it was done. I won’t hesitate to get my next car done.

This is the first time I have used Celtic tuning, although I have been thinking about using their services for a while. The service is excellent and whole experience is painless. I am now wishing I had taken the plunge earlier. The result from the remapping is phenomenal. Power delivery is so smooth all the way through the rev range. I wanted the performance of a 530D, I think it’s better plus initial calculations show an improvement in mpg. I’m told that over time the remapping learns and improves, can’t wait. Great service, great team and great results.

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…
