Yeah if you have an AP they have a CA/NV/AZ 91 map for you.

Your in my same boat (l live in AZ) Take note though, if you go with COBB and you have to use CA, NV, or AZ gas, a stage 1 with an intake might give you more HP than a stage 2. I'm well aware this sounds ass backwards, but I have a '10 WRX and have to use AZ gas, and COBB's stage 1 with intake will give me 11.7% increase vs their stage 2 with intake will only give me a 9% HP increase. COBB's tuning focuses on better (93 octane) gas. Just a thought, always can go with a pro-tune route if needed

huh...is it that much of a difference? Im on the reg stage 2 now. WHat will the change do?

My mods a pretty basic. An upipe, down pipe through 3" all the way back. All catless. And then i switched my stock intake filter to a k&n one. Not too many mods....but the ap helped w/ the power. Feels a lot smoother and gets from 70-100 much quicker

I'd call/email COBB or whoever you have your off the shelf tune by and see whats best (they might even be able to make a custom map for you). It sucks only having 91 octane when all the tunes are best for 93. I still think your best option would be to drive to Sac or Reno (assuming there's no pro-tune shop in Tahoe) and get a pro-tune for 91 octane. An example of pro-tune vs off the shelf would be: Cobbs stage 2 with intake for 91 octane will give my '10 WRX about 24 HP at the flywheel, whereas I can get a pro-tune at Dyno-comp in Scottsdale and get about 70 HP at the flywheel with the same set-up.

^^ya one of these days.....not too worried about it atm. I have a few more upgrades id like to do before i get a protune. Im on a budget so this minor upgrade was worth the $160 for the v1 ap
