Interestingly enoguh, even though my ISC works, my rpms still drop when I turn on the AC? Whats up with that?

What is your ISC counts for idle.Also what's your TPS volts at at idle now? When I deleted my FIAV I had to bump my idle to about 900RPM. Before that when I would turn on my AC my idle would drop really low. Now it jumps to about 1050RPM for a sec and settles down at 900 again.
