2003 Audi TT 225HP Tuning for stock turbos ?
#4
Just go with one that is available at a local shop close to you. The differences between them are minimal. But in general APR is a little more conservative, it has been around the longest and poses the fewest quirks because it doesn't push the envelope. REVO, GIAC, and Unitronics will gain a little more because they push the tune a little more.
