Please tell me you don't tune any cars. The difference between MID 11s and LOW 12s is quite a bit even though the math says differently.
Not sure what to tell you. Most tuners I talk to stick with MID 11s and state the gains aren't worth it. Most of my friends with modified cars (ranging from various platforms) stay right away from 12.X anything especially on pump gas. I'd agree that it's more forgiving if you are runnin higher octane but don't see the reason to take that risk.
