I have the 93-octane program on my GT and am having no issues.

However if I ever have to go back to "factory", how do I do it?

I reviewed the downloads after upgrading and there's no "factory" entry, just the new 87/91/93 from Brenspeed.

I must be looking in the wrong place.

Thanks in advance for any help.

Without having one in front of me to look at I can't remember the screen, but your XCal removed your stock tune and stored it. And there is a "return to factory" parm.

If you have the SCT tuner, when you get to the "Custom Tune" screen you should be able to scroll down to "Return to Stock" from there.
