Kev, speak to Phil before Monday and see if his mate Darren who does some remaps can do you one for this one. He lives in Grain, so not too far away from where you will be.
He did one for a friend who had a 530D M-Sport on a 2007 model and the fuel economy went from 38mpg to 52mpg and if you turned the TC right off (hold button for 3 seconds) it lit the rear tyres in 1st and 2nd on the autobox in the dry (as Phil will testify to as passenger
)
