forced induction is the only logical solution to your problem. the truck might seem like it has no power do to the slightly larger tires but you shouldve picked up about 50-60 hp with your setup. im running cai and high flow throttle body on my '07 5.4 and i feel the extra 25-30 hp i picked up. you can put cams, brian crower makes some, comp cams, and crane cams as well.
