Hey, I just had my 98 GT chipped(diablosport) and dyno tuned at a reputable dealer in my area. But I have a big problem now and I dont know whether it is because of the tuning. My car will stall out and I lose all power functions. This happens at any and every speed. Also, it will cut out sometimes if I press the brake pedal. If I turn the engine off and restart, it seems to work ok for a time. Any help from anyone with experience or knowledge with this issue would be greatly appreciated. Thanx!
