    I have an 04 twin turbo cobra with fast xfi and xim with stock computer and ls1 coils the car is breaking up at 2000 to 2500 rpm then again at 5000 my buddy disconnected the cam sensor from the stock computer and he thought the problem was fixed. Car had an optimal battery and it was going dead do to age so I got a new battery that was equal to the optima with top and side posts the fast is run of the side posts. Can anybody give me any input of what could be the problem
    Thanks Gary hunt
