ok here the situation my 2006 Evo 9 MR has had cold AC since the day i bought the car in February of 2006 up until a recent track event where the only thing different that i had done to the car was i put on 275/40/17 r compounds drove the car half day ( because i was losing boost and couldn't find out why until i got home and notice one of my intercooler coupling had a huge tear in it) but from that day on the AC doesn't work............ i am thinking that i need to have more freon put into the car but was wondering if anyone else had the same problem
