You have to be more specific.

It idles high after you hit the gas? That sounds pretty normal.

How high does it idle once it's started?

How long has it been on the car, and how long has it been doing this?

You might try disconnecting the PCM for ~30 minutes and then letting the car relearn its idle. You might also have a vacuum leak after putting it all back together.

It sounds normal to me. Hell, my A4 would idle @ around 800-1k rpm for a second or two on initial start up then it goes down to 500-600 rpm. This is w/ non ported and ported TB.

Yeah, mine will stay about 900 coasting after I accelerate then it goes down a few seconds later when I stop.
