Well, it would be the same as if you were to disconnect the battery to install something and left it unhooked for an hour or so. No difference to a Jeep; no power is no power. Once the PCM loses its power and all its backup power, it will shut off and default to either its stock tune or the last known tune, which would be Superchipped.
Plug the tuner in and see if you have anything installed. That would be the best way. Then, you can return everything to stock with the Original Stock Build that's saved in the Paq and then reinstall all your tuning.
