Ford performance tune calls for 91 octane minimum, 93 octane recommended. 87 octane negates any benefits from the tune and seems to go back to a more standard power curve.
They charged one hour of labor. I set up the Ford Performance account and registered the tuner, and then provided them the log in information when I brought the Bronco in.
One easy way to tell is to turn off your auto stop/start, shut down your Bronco fully, then restart. If the auto stop remains off the tune is installed.
