Hey there people, basically ive got a standard 06 plate gt tdi (140) done about 127,000 miles
Only mods really done to it are sounds but now im really thinking about getting a remap or some sort of tuning done to the engine.
Ive never really had a vehicle remapped or chipped before (not even modded to be honest)
Main questions are:
1) what are my options for remapping or tuning as in who are the best people to go to. Im in the west london area
2) what power increase or even mpg increase would i roughly gain
3) If i am thinking about putting wheels or lowering the car, should i remap before or after this
cheers for any help all
