Hi there, I'm new to the forum, I'm looking for some advice. I am thinking of buying a tuning box for my pride and joy, A3 2.0 tdi black edt. I've been told by tdi tuning it's very easy to install ( 10-15 mins) even for a beginner like me it's very well priced and will improve my bhp, torque and fuel economy, any advice, thoughts much appreciated.
