I have a '72 SS Camaro ls1 m6,ms3,prc 5.3's,ls6 int.,p&p t/b,all bolt ons,3" exhaust ,no cats.Car was tuned by Geoff Skinner & was great!!!I have since added a fast 92/92 & long tubes in place of Mac mids.The idle willusually hang about 2000rpm until you stop moving & search for a while & recover.I am using HP Tuners & have been making adjustments in the Throttle cracker as well as some in the Base Idle Airflow vs Coolant Temp. with very lil success.Am I in the rt tables for this ?Thanks for any help!!

You will need to tune your MAF table for the new intake and throttle body. Do this first.
See if returning the throttle cracker to stock values helps the hanging idle.

Thanks I have been real busy at work & have not had much time to mess with my car.I did reset the TPS with the blade open just a hair more & zeroed out all of the throttle cracker.The car starts & idles near perfect most of the time but the idle still hangs about 1500 to 2000rpm about 50% of the time til you come to a complete stop,idle return is always stable with no searching.Exactly what should shooting for in the MAF tables/parameters?Thanks for any & all help!!!

Start with re-calibrating airflow tables such as the VE, MAF, and running (idle) airflow.
