depends on who tunes your car. w/ good tuning you should be able to get away w/ 94 octane.

so does reno. ****** we get all the california shitty gas. i run on 91 octane w/ 12.5:1, but i also have huge bc4 cams to reduce the cylinder pressure. with some proper tuning, i think you can get away with it.

Re: 12:5:1 help (CptCorN)

I was running 12.5:1 on 94 and having issues.

I knocked it down to 12.0 with a turbo head gasket. If you are daily driving it I would stay around 12 to be safe but thats just me. We took TONS of timing out of it and it STILL hated pump gas. Now I run 93 - 94 with absolutely no issues.
