Hi all, im now in the hunt for my first A3, i have narrowed it down to the 2.0TDI. I have read that there is quite a noticable different performance wise between the 140 and 170 models. Im struggeling to find many of the 170s with the spec i am after, so my question is, is it easy enough and cheap enough to chip/remap the 140 to give it a similar feel to the 170 and how will it effect the fuel consumption etc in doing so? Im looking at the black editions and like i said cant find many that suit all my needs/wants. Cheers for any help.
