2.4 liter power with A/C on

My car has a serious lack of power with the A/C running. I have the 4 speed trans. It seems like I almost have to floor it from a stop sometimes just to get it going. Is it just the nature of this engine/trans combo?

I haven't driven a 6 speed 4 cylinder. Is it any better? Anyone here with a LS 4 cylinder/4 speed have this issue?

With the A/C off it runs much better so I'm thinking that if I complain to the dealer, they won't or can't do anything about it.

Any thoughts?
