i didnt think i had enough mods to need that much fuel but this aint the first time ive heard that, u dont have a clue as to whether or not it may me something else

changing the heads on a 5.0 from stock is a pretty big change. thats one of the worst parts bout the mustang they have real small heads. the bigger the heads and the aftermarket intake the more air ur gonna move n if u dont have enough fuel it will make u run lean
