I removed my Pc, Ec, TC harness to keep myself from abusing power during engine breakin (thanks Tom). Anyway I just took a turn around the block and my AEM is showing 12:1 under WOT. Seems like kind of alot for NA. I don't remember what it was when I had the harness in with the belt off the blower. It dithers between 14-15 at idle like it should and cruises at a reasonable number. Any ideas?

Actually that's pretty normal. The 05 when stock tipped in at 13 and dropped to 12 a little over 3000 RPM and stayed right on 12 to redline.
