    engine boggs when a/c is activated

    Just put new induction from air lid back. Everything works great lots of power and pull. However, when I turn the a/c on the engine wants to bogg, it goes down to 500rpms and acts like it wants to stall. Anyone ever heard of the problem.

    sounds like the idle air control circuit is all out of whack now. You definately need a tune because even if you just turn the idle air control screw your rpms at idle will be much higher. Try messing with the screw on the side of the throttle body a little. Flip the ac on and off and adjust it till it feels ok. Don't get too carried away. A 1/4 turn will bump you up a couple hundred rpm's.
