I'm thinking of having my 2005 A6 2.7 TDI Avant remapped.
Has anyone had this done and who is the best place to get this done as there are load of companies sprouted up over the last few years. I would need a good reputable one.
Please let me know your thoughts and experiences.
The main reason isn't for performance but for mpg but obviously more performance is a part and parcel of this mod.
