Anybody shed any light as there are so many tuning options avialable.
Looking for a unit that plugs in and can load a map for power / economy / original
It will need to be smooth with power coming in all through the rev range.
The car will need to go on a rolling road as want it done properly, plus have good customer service.
To much to ask lol oh and its for an A3 quattro tdi 170bhp on an 08 plate.
