I had my Mini Cooper SD remapped and EGR deleted. Very pleased with the fuel economy which averages out at 52mpg per tank of fuel. The performance of the car is fantastic and very happy with the results. Josh the owner is very knowledgeable and a great man to deal with. Highly recommend.

When my cars clutch had worn to the point where it was undriveable, Josh managed to get me in the following day to fit a replacement and I was driving again by the afternoon. When seperate issues made themselves known after this I was always able to get it in next day to be sorted. Always friendly and would 100% recommend.
