Thinking of buying a k03s turbo for my AUQ
It's an A3 1.8t 20v and going to be fitting the turbo in the next few day's
Should i fit this turbo before the Revo map or after or does it not really matter?
Here's the link to the turbo, i'm sure this will fit but i'm sure you guy's will tell me if it doesn't...
