I'm sorry, but over half of the people who read this forum have available to them >91 octane fuel at the pump. When these people dyno they often only post their top race fuel boost level, when often that car will never (at best rarly) see fuel like that again. Why? For bragging rights. The point is we (those of us with 93+ octane fuel available AKA the MAJORITY) want to see BOTH charts. The pump fuel chart and the race fuel chart. If there is no point in tuning for your 91 octane in CA then fine - only post race charts. You have an excuse. BUT THE POINT IS: MOST people don't live in CA, MOST people have 93 octane avaible at the pump, and MOST people still only post their race gas high boost dyno charts for bragging rights.
