And no I dnt have a tuner I had to take the gotts mod off a couple months ago cuz I had to pull the battery and when I put the battery back in the pcm was reset and it ran like crapp so I put the stock intake back on also so its not a prob with the MAF.

Correct. Only the 3 valve engines have cam phasers. The 2004-2008 4.6 is the 2 valve engine.

The 5.4 has a longer stroke than the 4.6. Bore is the same.

Your chain has been yanked.......Ask him to see the part that he recommends you replace, then post a picture of it here.

Do you see it on your engine? If so, then take it off, clean it with a carbon deposit cleaner and then see if it helps. I had one on my 01 Superduty with the 5.4 and my 04 Focus with the 2.3 and my sons 96 3.0 ranger. Never replaced one, always just cleaned them. I think I used GUNK foaming engine cleaner and a pipe cleaner to clean them. Its been a while though.
