well i originally had the sohc greddy kit.. and now i upgraded to a t3/t4 and did a bunch of other upgrades and now that i have got my car back it has slowly started over fueling and now it does it whenever it wants.. like sometimes i can give it like 30% throttle and its ok then other times it will over fuel like crazy.. doesn't matter what rpm or anything.. just whenever... i am running the hack right now.. its all set at -40% across the board.. anyone help me out or point me in the right direction i would greatly appreciate it.. thanks
