I have always said the exhaust system on a S3 is'nt great and you can get a very good gain from a larger + better flowing system. How loud is it now compared to standard.
When you get a silicone TIP your car will peak to a couple more g/s and will run a bit higher in the rev range before your off boost, mine was about 300 - 400 rpm extra according to the graphs I did at the time.
If I was you, I think I would reduce the timing a bit and let the ECU adapt to the changes in exhaust air flow and boost pressure. Your car may make better figures now but the drive ability may be sacrificed a bit due to all the changes you have done without having a map to control it all. Let the ECU settle and upload the REVO stage 2 software then play around with the advancing the timing etc.
Im going REVO stage 2 in a couple of months and would be good to compare my results with yours.
