| Upgrade your Evo Upgrade your Edge Evolution to a Gryphon Programmer to allow for custom tuning and additional functionality. Due to issues with the cable failures due to incompatible versions of firmware, we do not offer upgrades or tuning for the 1997-2003 F-Series gas or 7.3L diesel trucks. We recommend using another platform. |
