550 miles is about 50/50 highway/city. Its at 700 miles now and I am still taking it easy. I will wait another few thousand miles before putting the tune and short shifter back in. Also have Roc Euro intake sitting in the basement.
Tried acceleration again this morning and the sensation of lighter than usual clutch pedal is still there, but not as noticeable. Another Audi tech drove my car this morning and said the overall feel is normal for a new stage 3 clutch.
So I am more comfortable now knowing all of that.
Thanks for the response, Jimmy!
