I bought a used Gryphon on F150 Forum. IF it was returned to "stock", does it contain "canned" tunes or just custom tunes? If it contains the canned tunes, I assume I can just plug it in and use it? I plan on doing a custom tune when I have time, but will be home tomorrow and the Gryphon is there waiting on me, so I want to get it hooked up for the weekend.
