Does anybody know what the IAC counts should be on a blown car?? Mine are around 125 to 141, and I think that it is a little high.

way high. around 30 out of gear at idle. around 120 in gear at idle. check this link http://ls1edit.slowcar.net/tuning.html

Any idea as to why my IAC counts would be so high?? Vacume leak, IAC motor not functioning properly, anything??

you probably just need to drill your T/B plate. i used a small unibit and checked it on every step of the bit. in MY case it worked out to ABOUT 20 IAC points, your may be different. one suggestion, once you get around 50, go drive it for awhile and check it again. have you done any other mods? a vaccum leak would make them lower if anything. if they don't change, then there would be something wrong with the IAC.
