My understanding on the suject is that the maximum timimg is programed in ECM and unless you reprogram the timing to take advantage of higher octane (advance), extra octane might refrain timing retard when knock is detected with 93 (100 would be more resistant to knock) but would not yield significant hp.
Just my thought.
