Idle with Air Condition on.

[Accelo]

I just charged the Vintage Air I have installed on my LS1 motor in my C10 truck. The LS1 has a BTR Stage II truck cam installed. It idles fine in or out of gear without the air on. However, with the air on the motor surges and struggles to keep running when ever the pump kicks in.
Background is the motor is stock except for the headers and cam. ECM has not been tuned nor has the motor done any driving except for idling in the shop.

Since the Vintage Air is not connected to the ECM in any way I have to assume the idle is controlled by the idle air control. Doesn't seem to controlling the idle with the air-conditioning running. Maybe it's just chasing it's tail.

I'm thing I shouldn't worry about this till I get some miles on it and the computer has had time to learn.
What is everyone's take on this? I am all ears. This is my first LSx swap.
