Default Surging Idle

A little background:
After driving my car to work today, for the first time since installing my program, I've noticed a problem with the idle. If I drive for a bit, go through the gears, and come to a stop. It wants to fall flat on it's face, 200-300RPMS, sometimes even dying, if I rev it a bit it'll stay up and running and eventually go back to idle(800-900 rpm's) I know it shouldn't do this. I've got HPTuners, what do I need to adjust to get it to idle right? I'm pretty much a newbie so if someone will explain in easy-to-do terms. Thanks guys!

Mine used to do that as well, I was running pig *** rich before I cleaned up my VE table, that helped TREMENDOUSLY! To fine tune after that I turned off my Closed Loop Proportional Idle table and bumped the idle from 800 to 850 at operating temps and my idle holds very well now! it'll surge a tad bit when at a stop but nothing more than maybe 100 rpms.. If i'm at a light a rev the motor and release quickly, it will drop to 500 for a second but raise right back up to 800ish as sit quite nicely... I'd say work out your VE and see if that helps!
