original predator 6.0

I received my 2003 Ford F-250 6.0 automatic two wheel drive from my father when he passed away. I know this Predator has not been hooked up to his truck for quite a few years when I hook it up and tells me that my truck is not listed I have pictures of what it says I will add them. I cannot change any of the Tunes. Any help would be appreciated thank you Jarrod.

the truck was updated by ford at some point and now the predator needs to be updated to support it.
If the tool is married it needs to be reset first, then updated and it should work again.
