hew to ford and the forum. 05 fxa scab. 5.4 . magna flow single muffler and a k n drop in. how much more power from a cai? exhaust and drop in made a little difference. motor still seems sluggish. almost seems like it is always in to high of gear when takeoff is 2 grand or lower on tach. if i get on throttle a little harder in low gear, like winding out to 3-3500 everything seems better. except fuel mileage. i plan on programmer and other bolt on mods eventually. would cai be better first or programmer. just leveled front today. huge difference. truck looks so much better. i think i need a sponsor for tires and the rest of mods i want. any advice is appreciated. what should 0-60 times be on this truck? last question truck only has 16k but the tires seem to have wore way more than that and has small cracks. i read somewhere about a premature wear recall. i went to local dealer and they said no recalls
