Question what would cause this?

if when im driving on the freeway at about 65 in 4th gear and punch it, the car should pull pretty hard since thats where the cam shows its worth. Well for some reason it has no pull to it anymore i though the clutch was the issue, but after changing it out from the spec 3 and stock fly to the ram pg hd and billet flywheel, its still doing it. My gas mileage is also very shitty still. a mix of city and highway and im only getting at best 12mpgs. its only a f10 on a 114. Guys ive checked the tune and all seems to be fine. Ive had Allan at Futral check it out and Sean at Fastech and fof667. LTFT's are 0 or -.8 when cruising at 2500 rpm in fourth..about 55 mph. there's no vaccum leaks, o2's are working properly, I havent gotten a current a/f reading since i havent tuned the WOT, but its either at idle or cruising that my gas is getting eaten up! Im using 91 octane as well. You all have any ideas on what it can be? If this is the wrong forum, please move it to where it needs to go.
