DJ, keep in mind S3 will give you more & more power as it tunes itself. Right out of the box it starts mello, then adds timing as it feels comfortable. Just stay out of knock. It classifies knock 2 ways. Short term & long term. Short term it just pulls timing till it sees no knock for a little bit. Long term it will basicaly go back to original timing or worse & will wait a long time to watch your good behavior before it gives your timing back.
As far as boost goes, give it a chance to get to 20-21psi. THat has been pretty normal. Also remember S3 is not looking for a boost level, the ECU is looking for a calculated power level. If you can hit that power level at 19psi, then it is only going to give you 19psi. THe bottom line is you need to give it some time to see what the ECU is going to do. before you should start monkying with it. Most guys that have turned up the WGA on S3 get lowered back down by the ECU. It will literally vent more boost on its own to get teh PSI back down. Give it time.

I had a stg2 pcm on with stg3 and holy sh!t. It was a night and day difference from the stg2 to stg3 pcm. I don't care what anyone says, you will have more fun on the stg3 pcm.
