I know that the major difference between the 2 are that the Gryphon can be custom tuned, and also that the Gryphon has a black housing instead of the Evos silver. Other than that is there any difference in the canned tunes?

I have been thinking about up grading to the Gryphon, especially after today when I was helping my father fill out the order sheet for a Gryphon and custom tunes for his F350 7.3L. But I not really sure that I want to spend $200 right now for the custom tunes, being that there aren't a lot of new projects coming in at work right now and also with a new baby that takes priority over everything.
