05h2sut: BAD IDEA!! I can get away using the 93 octane tune with low octane fuel because of the altitude I live at. Octane requirements become reduced at higher altitudes. Your at sea level (Rhode Island) and running the 93 octane tune on low octane fuel could result in pre-ignition/detonation with can damage your engine. That's why Diablo has a warning/disclaimer in the user manual about not programming the 93 octane tune on lower octane fuel.

For an explanation, scroll to the bottom of this Wikipedia article and read the section titled "Regional variations."
