how do the big cammed street cars do with the AC on. I was thinking about an MS4 but I want the AC to run perfect as normal. (TEXAS) I remember in my 6spd with hotcam the car would die with it on..but it was never tuned. Is it all in the tune?

 

hell yea it's all in the tune. My MS4 A4 SS daily driver has zero problems idling or with the way the AC works
