I have a 1994 Cobra 5.0 w/ a P600B Procharger and 66k miles. When i try to floor it in what ever gear it starts to sputter, BADLY. its worst at 5th gear. Ive concluded it has nothing to do with rpm, just throttle related(something not working in fuel, air system?)

Rick; There are so many possiblities here with the mods. The first thing I'd check would be fuel supply. KOEO pressure should be 35-45psi. KOER should be 28-45psi. Might want to check the TPS for a 'glitch' in the WOT position? Also, timing curves.

Sounds like maybe timing may be off some, bad fuel regulator is another suggestion. Does it idle rough? Any codes? Could there be a blockage of exhaust maybe?
