Canned tunes should work, custom tunes will not.

And, to return to "canned" tunes so that your Gryphon will work on the new truck:

1. Set your old truck back to stock (Level 0) BEFORE you remove the Gryphon!
2. Start Pegasus on your PC.
3. Plug the Gryphon into your PC. When Pegasus tells you the Gryphon is "connected", click on [Updates]->[Gryphon Update Manager]. You should see a firmware and a calibration update available. Apply them both.

Now the Gryphon should work on your new truck.

The canned tunes will work but new custom tunes will have to be ordered and written for the new truck......
