My 2005 GMC 2500hd is in the shop currently for some work. I am running the U7185 that i returned back to stock before going in, and now the shop can't do anything as it is coming up with ECU LOCKED. Shop tried another ECU, and they can access everything fine. Is this an issue that i can solve with my tuner?

Cant lock it with a Predator....if they were able to restore it with the Predator, see if they can reload the tune from the Predator.
