OK so i just bought the gryphon. I didn't get customer tunes. If i do the gotts mod in-between using the gryphon and ordering the tunes. do i need to let them know. i already filled out the ordering sheet for the gryphon saying no to intake mods, but am going to do the gotts mod.

You will not need custom tunes with the gotts mod and if you didn't get custom tunes then they don't need to know anything about the truck until you order custom tunes
