When I purchased my truck, it had 40K miles, and almost new looking factory tires/rims. Makes me think the PO put on aftermarkets, adjusted the speedo accordingly, and returned to stock wheels/tires when the lease was up???

I think you've got it! Or, the PO never adjusted anything - some people don't. Bill didn't say, but from other posts, I gather he has a way to make the Gryphon play with your PCM even if there IS a custom tune already in it.
Yes, though, the Gryphon's tunes start with the premise that the PCM has a stock tune installed.
