ATR proficiency, anyone?

As many of you know, my car was boomtastic and I had to rebuild. She is running well now, but due to the head work and compression chance, my engine profile has changed quite a bit. The only issue I really need worked out at the moment is the idle. I get too much air flow at idle, and fuel can't keep up, so I get 25%stft's and 18/1 afr at idle. This was corrected briefly when using a cpe standback (Thanks Jeff G) by adding 15% more fuel at idle, which elevated pump pressure to the 600's, but afr's and stf's were dead on. For some reason, he wouldn't let me keep his standback, haha, so I need to attempt a similar maf/fuel adjustment with my AP. I fired up ATR and was ready to do work, but backed out since I don't know what the hell I'm doing with it. Anybody around the Streamwood are that knows ATR and is willing to help me correct my idle so I can drive it more comfortably until it is broken in enough for a full tune? I really appreciate it!

outside of P&L, jeff is probably your best bet

I really need to get on the ball and start working with ATR. Once I am "done" with my car I am going to have a pro tune it but until then I really need to work to tune it on my own. ATR appears to be a rather powerful tool if you know what you are doing, but at the same time it can be dangerous IMO if you don't know what you are doing. If you check the AP thread on the 6 portion or this forum there are several guys with some great incite as they have been working with ATR for a while.
