93 just adds extra insurance. The tune will run just fine on 93. If anything you will get more consistent power even after many many pulls when things are heat soaked. For example, when people here in CA run their cars on the track, many put in a few gallons of 100 octane. Not for power, but for consistency and for insurance.
