Hi guys,
what tables to correct hanging rpm's on the start up? when I start the vehicle it goes all the way to 2000Rpm's and hangs up there for 2-3 seconds then drops slowly to the desired set rpm!
any thoughts on how to fix this?
Thanks,

Hi Joe,
The car runs great making 400/400+ rwhp & Tq on a 6.0, untouched rectangular port heads and a 220/230 117+4 cam on a truck with 32" tire .
Still believe it needs some fine tuning at idle and such...etc.
I played little bit with table B4604 [Startup RPM Offset] and seems that the problem has been resolved. But not quite sure if this the correct approach in such issues.
Any suggestions?

There's an idle tuning tutorial thread here, let me find it.
