1990 mustang gt 5.0 running like crap after 2500 rpm
i have a 90 gt with 302 has trickflow streetheat intake, 75mm throttlebody, 24# injectors, 70mm ford maf with 55mm stock 5.0 maf sensor, f303 cam, gt40 heads, msd ignition. the timing is set at 10 degree btdc, it will idle fine but when you get on it it sputters after 2500 rpm and im not sure why i have 31psi of fuel pressure with vaccum line connected

ya 31 psi should be good wit the vaccum line hooked up unhooked the psi should be like 39...........im goin to get a pm or a c&l maf hopefully that fixes the problem.......also i have a cracked distributor module idk if that has anything to do with it cause it will idle fine and run fine up to 2,000 rpm but after 2k it runs like crap spittin and sputterin
