I can't get my car to stop idle hunting once warmed up and It is getting really old. The idle adjustment screw is all the way tight, I have let it idle for up to 1 hr to let it learn. It has to be something else 
Also I have no vaccum leaks and everything is connected. It is starting to drive me crazy

Open loop is when the O2 is disconnected right? Or is it the other way around? Currently the 02 is connected, but I turned the o2 sensor option off on the commander. I will try disconnecting it and see what happens.

If its off, it shouldnt be the problem.
Next idea. Are you using the pill in the boost sensor line? Fluctuations in vacuum from a ported engine could cause that.
