i have a 93 mustang with a 6.0l, l92 heads, gmpp intake, holley 750dp, msd 6010, car stumbles and goes lean at wot, ive checked acc pumps, they seem to b working fine and in adjustment, changed power valve with no change, checked for vac leaks besides spraying carb cleaner or somthing around base of carb havent done that yet, anyone else have any options for me? cars tuned on e85, seems to be fine besides the stumble at wot, i usually pedal it and it comes out of it but it kills the 60' time.

e85 will want a lot more pump shot, probably at least 50cc kit in the front with 40/40 squirters in the carb if not larger

the cars been built for awhile and has been dyno tuned, the setup should be good.

Sounds like a fuel delivery problem. Alcohol is a solvent, checked the fuel filters lately?

i would guess its fuel delivery also out the hole.
