Gotcha that makes sense. The reason im asking around so much is because I know 2 people with stage 2 91 tunes in the LA area and both of them run the regular 91 octane. I don't have contact with them too much so I figured Id ask around to get some input from a couple people. I think im gonna play it safe and stick with the ACN91 tho.
