I just had the Unitronic Stage 1 Tune done on my 2006 A6 with the 40v v8 and there is not that much of a difference in feel. Slightly better throttle response and it pulls higher in the revs better. I like the fact that the top speed limiter is gone. I had it dynoed before and after and showed gains of around 35 horsepower and 20 lb-ft at the crank, not huge gains but an increase
