I know you said you don't want to mix e85 but it really is the best way to run the sport or aggressive maps when using CA gas. There is a station in Ventura called Silvas Oil Co. that sells e85 and I drive down from Lompoc every few months and fill up (5) five gallon jugs and just keep one full one in my trunk. But like everyone said, just log your car with the different maps on regular gas to see how your car responds.
