I think I'll try the 91+ tune and premium for the next couple tanks. That's one of the benefits of the Autocal; they emailed 3 tunes to me: stock, 87-89 octane, and 91+. It only takes a few minutes to change between them.Oh I see. I lay into mine here and there...but am usually nice to her lol. Yep i'm running premium-always have been since it was tuned. I do get better mileage when I find non ethanol premium-but that is usually up north only.
