myself and 05sti went to Orlando and on the way back we decided to do a couple of runs just for a little fun so we went from 65 in 4th gear right as i was about to shift about 6250-6500 rpm the car just lost power kind of hard to explain but what i would think boost cut would be like but i dont know right after it happened i got a cel but when i started the car to go to work last night no cel so i wasnt able to get it read

Jeff
