I finally overcame my apprehension and took the Gryphon off the truck, plugged it in the laptop w/ Pegasus running, and had to go back out and return the truck ecm to stock.

Happily, the Gryphon forgave me and connected back through Pegasus, and it allowed me to access the custom downloads from the internet. I never had a problem with Gryphon staying red, and thankfully it turned out very straight forward. The test drive was very satisfying.
