Thanks for the info, is there anyway to tell if this has been done? I just got my jeep a couple weeks ago it had a previous owner

You may or may not have sticker in engine bay. Chrysler may or may not have information about it being performed in their computers (dealer can look up by VIN #). To know for sure dealer can hook it up to their "software upgrade" computer and check it.
