kinda hard to explain so if we take off in first the speed shift into second it boggs / sputteres right wen u hit second then pulls normal again it does that through every gear unless u shift normal then it's ok I jus found out he's runnin irridium plugs gaped at .044 so he bought sum 7s I'm gonna gap them at .028 see if that changes anything also he has rc 550 injectors but no resistor box so not sure bout that the car is tuned so I'm sure tuner would have said something if he needed one
