Take air out (less air). Sometimes I will use a 2002 Z06 M6 Throttle Cracker Table for Starters.
Occasionally you have to mess with the Throttle Follower Tables. I'll drastically lower the TF Decay Delay, B4318 from the stock 3 seconds to 1 second to get rid of the annoying length of time for the idle to settle.
Again most likely Table B4309 will solve your problem. As an experiment you can also make that entire TC table Zero's. Your idle will never hang. Just depends on your preference. Rpm's will drop rapidly. You may not like that much engine braking.
Give it a shot. Good luck.
