Unless something's changed, and I don't think it has, your upgraded Gryphon comes with the tunes installed. This let's Bill test that the tune and firmware upgrades went in without problem.

Like Jack said, it comes with the tunes loaded. It's nice that Bill goes this route, though it takes a bit longer to get your programmer back; you eliminate the possibilities of errors downloading and installing them on your PC. It's worth the wait too.

When i received my upgrade to gryphon i just plug it on the truck and load the custom tune. I did not had any problems.
