I have a 88 carbureted mustang. It's a 302 bored 30 over with forged pistons with stock crank and rods. It has a very tall intake with 750 holly carb. I hooked up a Nos cheater system set up for a 100 shot but never used it yet. When I push the pedal all the way to the floor it will studder but when I drive normal or semi aggressive it's ok. I changed the plugs, wires, and had the carb worked on. I was told by someone it could be the intake is too big for my application or maybe the electric fuel pump isn't enough. It's a Mr. Gasket 12s which only has 35 gph and max 7 psi. I don't know the make of the intake but it's probably 3 times as big as a edelbrock performer. Please Help.
