    It all has to do with how much boost one adds. If your using just the module with a stock intercooler, 93 octane is fine.....except for extended full throttle. The stock IC will heatsoak in about 20+/- seconds, and the ecu will reduce rpm's.

    If using the Stage 2, 93 octane is fine....even up to 17 psi boost level. Higher boost will need more octane. Just mix in 5 gallons of 100+ octane race gas to a full tank.
