R28 to R30 no more RKL???

[Turbo606]

I have a 2005 CTD. Had the predator with the R28 version. Ungraded it to the R30. Made sure truck was back to stock program before loading new R30. I went to the post R30 custom tunes and now I Can't load a extreme RKL into my truck. It loaded ok from the computer to the predator. But when I go to load the extreme RKL into the truck it say that I have an AK at the end of my calid and the extreme rkl tune I loaded has a AG. What give's?? it worked pre R30 with RKL tunes and now with the post RKL tunes It doesn't work. my calid starts with 25********ak.

Did you load the custom tunes before you took a backup, i would load them after you have relocked the predator to your truck.
EX. Load any diablo tune into truck then go and load the custom tunes to the predator and see if it works.
