Hey Corey? You guys are now saying you can not upgrade the Gryphons from earlier models to work with the 09-10's? I held onto my Gryphon when I sold my 06 because I was told that it would be able to be updated to work with my 09. What now? It has been loaded with custom tunes that worked great with my old 06, but that truck and its buyer are long gone, as it was sold almost a year ago. Is it worthless now with these custom tunes on it?
Please advise.
