    In my own imaginary world, where. Respect for wome
    I run 93 when its down to 2.40 or so. But @ $3, its 89. I won't run 87 cuz I get better mileage on my 89 setting (SCT SF3).

    At our altitude I have to run premium in order to run just the Hypertech standard performance tune. 87/89 pings noticeably.
