Wow..... 600 hp!

A few technical questions: 1) the low boost dyno runs say 93 octane. Ive never seen anything but 91 at normal stations in Cali. Did you mix 91 with a 100 octane botique fuel to get 93? 2) the runs cut off at 7200 rpm. Did you lower the fuel shutoff rpm? If so, why? 3) The a/f ratio seems to be creeping up in the higher rpms, but is doing it on low boost and high boost runs. Is this the fuel system maxing out, or did you program it that way? And 4) since engines are just air pumps, to double your power you need to double the air in and fuel in... So doesn't that imply you need at least 1 bar of boost?

Thanks,
