Axlehead - Two things would have had to happen for you to get someone else's tunes and have them work.
1. Somehow, the other guy's tune would have had to be tagged with your Serial Number, and
2. You and the other guy would have to have matching HEX codes - Not very likely at all.
You got YOUR tunes, and, I'm glad you like them.
In case someone else reads this post in the future, some (all?) of the earlier model year units display "connecting to Bridge..." after the tune is loaded. It's kind of a "bug" and you can simply disconnect the Gryphon from your PC and install it in your truck.
