I've also began to notice that while in part throttle, mostly in low speeds, I can hear a faint, one second or less, burp from the exhaust as if for a second the fuel and/or ignition forgot what was going on for a moment. This is all while keeping a relatively constant throttle position.
I don't know if these are Gryphon related issues or if this is a ford related issue, but any help would be appreciated.
Thanks!

I cannot imagine how this could be tune related, but you could try returning the tune to stock and see if the problem(s) reoccur.
Backing a trailer is such a low speed, low power operation that it hardly seems possible for the tune to have any effect whatsoever. I wonder if you possibly have a dragging electric brake in the trailer wheel? I had that on my trailer (actually the brake mechanism broke) and pieces would "catch" in the wheel causing it to bind while backing. Moving the trailer forward and then resuming backing would free it. But, the permanent fix was a brake replacement, which I did.
Do you hear any noise in a trailer wheel when it is rotated by hand, forward and backwards, with the trailer jacked up?
