It's not just that this ball flares more than your others, is it? I know a guy with a SCB (diff of 0.075 or thereabouts) that gets 7+ inches of flare and the last flare line is almost above his fingers even though the first one is in a more conventional spot.
I'd say some kind of release change and to get your grip checked, but you'd probably notice if a span or pitch was off that much.
What about locating your PAP? Put a piece of tape on your PAP on some other ball, confirm that's actually your PAP, place another piece in the same spot on your Secret Agent and see if that's still your PAP.
