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.

So let me understand correctly. If the Gryphon can tune up to 25 hp then the 1997 5.4 with stock hp of 235 can now possibly be 260 hp. And with a 2001 5.4 with stock hp of 260 can now possibly be 285.
Can you tune the 1997 5.4 to be, or close to, the same as a tuned 2001 5.4 @ 285 hp?
I guess the point I'm trying to make is what year engine to start with to get the most Hp and Tq from. It seems like a waste of time to start with the '97 5.4 (235hp) if its not much better than a stock 2002 4.6 (231hp) that I'm trying to replace. Wouldn't starting with a newer year stock motor with 260 hp be better?
