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,

Post tune/log files.
How does it run otherwise...?

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?
