Hi, I'm looking for someone who can remap my 420d (x-drive manual gearbox). Of course I'd like it to perform like a straight 6 diesel if possible! but I'm not too concerned about the power/torque or economy. I'm more interested in removing/reducing flat spots at low revs to give a smoother drive. I read on the forum some great reviews of Jasons work at BW Chiptune in Essex. However I'm looking for someone with Dyno/Rolling road facilities in the Northamptonshire/Leicesteshire area ideally. Thanks for any advice/contacts.
