So, I live in the seattle area and i can only get 92 octane gas. Since all base maps for any EM solution only come in 91 or 93 octane, what kind of options do i have? I would assume the 93 octane maps will be too much, and the 91 maps too little. This leaves me with only one option which is get a custom tune. I wanted to just get an accessport since i didnt plan on doing any major upgrades that warrent a utec or hydra. I currently have a turbo xs stealthback, and would really like to get some EM soon. Thanks in advance.

www.pdxtuning.com have EcuTek maps tuned on 92 octane. They are based in Portland Oregon so pretty close to you as well.

Or just run 92 on a 91 map and enjoy the extra safety margin. I doubt the power difference would be noticable in any case.
