Which gryphon did you buy? You have to have the old mono chrome display unit for it to work as a ficm tuner. That is the first thing we need to know.
If it is, I'd use it for the ficm program. Program the truck, and if you decide you want more control, like egr delete, then you can change it back get custom tune for it, or buy an SCT and leave it as a FICM tuner only.
