Yeah I am pretty sure that didn't come out until 2007. I could be wrong but I don't think I am. My truck has this same noise and I think/hope it is just an exhaust leak. I popped the hood and listened to the engine at idle and I don't hear any ticking noise at all. I would have to say that my issue is exhaust. There should be a gasket between your Y pipe and the rest of the exhaust system.

I have another truck for trips, it is the same motor (well its a ly5 and mines lmg) but they both have afm. My other truck averages 15 in the city. There are lots of factors to take it tho! My truck is 6 speed, 3.08 gears, 5.3 lmg, and driven by me and gets 18. My other truck is 4 speed, 3.43 gears, 5.3 ly5, and driven by my wife, and gets 15. I dont think I have ever heard of an f150 getting 19 lol... honestly. But some of these trucks just dont get the mileage others get. Those factors listed are things people dont take into account tho. Gm is by far the best on mpgs. In the end, you bought a truck... not a prius!
