Is it possible to get one map for 93 octane and another for 91 octane? I use 93 as much as possible but am being transferred to CA at the end of the year (military), and I hear they only have 91 there. Anyway, I probably will only be there for a year, so I want the ability to switch back and forth (with the Simon, tool, of course). Or can the same tune be used for both types of gas? Thanks.
