Mechanically, the engines are relatively identical and yes, the tuning has changed over the years to increase power output. However, it's not all that significant.
The PCM code you indicated comes out to a ODAJ0D9.HEX calibration strategy. There is a 5.4L counterpart for that strategy which is ODAJ0E3.HEX (VMF3, Part Number 2L3A-12A650-VD) which is what we'd end up using as the base for the calibration. Not a huge deal, except for the PATS of course. We can either completely disable it or we can leave it intact but you may have to go to the dealer to have the keys reset. If you go with a programmer, we might be able to avoid the whole PATS issue entirely by getting a valid read from your PCM and using the PATS information to build you a set of files that are PATS compatible.
Let me know how it goes.

Bring back  Windows™ XP and 7. 
Windows™ Vista and Windows™ 8 is a pain in my a$$! 
Windows™ 10 is only slightly less annoying! 
Windows™ 11 is garbage! 
Much to my surprise, I'm actually quite enjoying Linux!
