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.

Just upgraded but have checksum failure

I got my newly upgraded gryphon back, went to install it and had a checksum failure. I came to tHis forum and read the FAQ and realized I forgot to turn my truck back to stock before I sent it in. What do I need to do to get this fixed? Thanks for the help
