Evo 9 stalls out problem

I know lots of people have this problem but I can't really fix the problem with my car. My car has intake, full turboback exhaust, forge bov and mbc, act clutch, cosworth cams and a full tune. Everytime i drive the car with the a/c on and come close to a stop or making a turn it will stall out on me specially in hot weather or after i beat on it. Anybody ever really fixed this problem on the evos. I know that there were people post this kind of threads before. Any inputs will be appreciated guys. Thanks

Your ISCV tables need to be adjusted properly. Also, consider upping the idle more when the AC is turned on.

I had the same issue with my Evo and when I had it tuned, they also tuned my ISCV tables and now when I turn the AC I don't notice a difference at all.

I don't thinks it's bad. Since it doesn't throw out any cel. Plus when I don't have the a/c on, the car runs just perfect.

Do you have cams on your car? And what does ISCV stand for? Because most people I talked to they said because I have cams that's why it does that.
