I found the Trick FLow kits like to idle with 14.5 AFR and about 35* of timing, may have to mess around with idle speed to get the car to stop surging, usually about 700-990, the higher end with an aluminum flywheel. I gotta get rid of the BBK throttle body too, I was looking at Accufab.  I got rid of my BBK fenderwell CAI, and replaced it with a 4" piece of PVC piping that puts the filter in the fender, and I moved my MAF to the top of the tube, between the TB and the tube. much better. I also messed around with the tune quite a bit, and now it idles pretty good, unless its cold. then it idles funny and stalls.</blockquote>
