    This post might interest you, it is about mail order tune. I think that is what you are looking for.
    Welcome to the site, nice to see someone from Wisconsin.

    +2 for getting a tune from Frost.

    is it the stock rear? If so you can check the rpo codes on the drivers door jam. If not you can either lift it and spin the tires and count the driveshaft rotations or mark your RPM's at a MPH and use an online calculator.
