New head/cam/intake/forged will not idle, ideas? Brand new forged bottom end, 30 lb injector, 227/230 TR cam, LPE CNC heads, ls6 intake etc etc..... The car appears to run nice at anything 1200 rpm or higher, the moment i take my foot off the throttle and go below that rpm the motor dies instantly. it doesnt even try to idle. Any ideas????? Do i need to adjust my idle up or drill a hole in the throttle body blade??
What can i adjust in LS1Edit to help this?

Re: New head/cam/intake/forged will not idle, ideas? Did you drill the idle holes in the throttle body at all?
Autotap and see what your IAC counts are right now, they are probably in the 130 range.
If so you need to get more air into the motor at idle...
You can try adjusting the screw but if you do too much of that it will set
an SES lite. I have typically drilled the tb's idle hole until the IAC counts are are below 50.
