hesitation with a/c on

When I stomp on the gas with the a/c on the engine hesitates. Anyone else notice this? I have no tune, just a k&n intake.

Whenever I stomp on the gas at any speed the engine hesitates because the traction control comes on!

I opened a thread further down. I had the same problem, got the new fuel pump TSB done and it seems to have gotten rid of the problem. Now when I hit the gas, the ECU disengages the A/C clutch and I get my power.

I got the fuel pump TSB done. My car totally runs better with the AC on now. However, the GT engine seems to hate super hot weather. I was in Vegas this last weekend and it was over 115 degrees. There wasn't a lot of power to the pedal while driving in the heat with the AC on.

Around town in So. Cal with about 80-90 degrees outside you get much more power out of the car then when it is over 90 (in my opinion). I assume that in super hot weather the computer starts getting creative in order to keep the motor from overheating, etc.
