Best CA Gas

Good ol' California gas, expensive and not-so-good grade compared to what people get on the east coast. I want to get a Z4 35IS soon, and eventually tune it. I've been reading up on the tunes and found that CA gas cannot give high output. Therefore, I would have to be on a conservative tune, otherwise i'd have to fork out $$$ on high octane, which I probably won't be able to afford. Does anyone have any good gas suggestions for aggressive/sport tuning of a Z4 35IS? Any input is greatly appreciated.

Dump in a couple gallons of E85 with the 91. I believe there are several E85 stations around OC.

are you kidding? E85 is the last thing you want to put into a high performance BMW engine. you're only asking for trouble you do that.
