Looking for Help Converting .tun

Is there any way to take the info from an EFI live .tun file and create/convert it to something a Diablo Predator could then upload? I know it would require somebody who has access to both EFI and CMR, so this could be a shot in the dark, but I'm trying to fix my mistake.

While messing around with the Predator I unintentionally ended up flashing over a custom EFI Live tune I had made for my 2000 SS.

I have a copy of the .tun file but no way to upload it back onto the PCM, and the Predator didn't store a copy of the custom tune.

Unfortunately I kind of live in the middle of nowhere with no tuning shops around, so this would be my only option short of mailing the PCM back to the tuning shop I originally had make the tune (car is my only one, daily driver).
