Here's the link to the 2015 Navigator fuel recommendations, note it indicates 'Premium recommended, regular capable' and the higher HP and torque than the Expedition (380/460 vs 365/420) have a * adjacent to them and indicate using premium fuel. That would lead me to believe they both have the same tune, but the motors won't pull back timing at boost as much when running premium fuel
