I am having exact set up as yours with OEM PCM and Cammed LS6.
The engine stalls and dies if I rev it when the vintage air AC is on. This happens when the AC clutch is engaged.
The rpm drops below the desired rpm and stalls. In fact, sometimes when letting off the throttle and pressing the clutch to come to a stop, the rpm drops and engine dies even before coming to a dead stop

If the IAC settings and base idle screw are adjusted correctly I would look at the Throttle follower tables. I've had this issue myself and adjusting the throttle follower tables allowed me to slow down the rate the throttle drops and eliminate the overshoot on a snap closing of the throttle blades.
