If it is 91 octane gas of unknown quality (such as may not be major brands), I would go ahead and reflash the 91ACN map, which is the most conservative map. You can still run this map with 93 octane gas. The other option would be to bring the AccessPORT with you and reflash (or realtime flash) the 91ACN map as needed.
