Gryphon Custom Tunes?
I currently have an Edge programmer on a stock 08 F150 5.4L.
I will be updating to the Gryphon later this year once all my mods have been added. I want to have a 87 Tow, 87 Perf, and a 91. Will a canned 91 work with all the mods (CAI, Cat back...) or will this have to be a custom tune as well?
