Utilised the eMotion2+ home tuning unit to apply the Celtic Tuning map to my 125d. The car already had some shove, but boost in torque really enchances the response and performance, especially through the mid-range. Request for minor tweak to map supplied within 2 working hours! Superb service, highly recommended.

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.
