    I was wondering if anyone has a 379 with a 3.70 rear lp22.5 tires 10 speed and Detroit and could send me a pic or let me know what there tach and speedo dip switch settings are? I can't seem to get my speedo dialed in right. Reads 5mph faster than I'm actually going. And I want to double check my tach as well. Thanks

    Dealer can't help? I would think they would have a procedure on how to set it up properly.

    There was a thread I started here about a year ago about this same issue. A member had the formula on how to set the dip switches but it was to much for me to comprehend. I just threw in the towel

    I called my dealer in Phx and got the run around. Was a joke.

    My guess is you would be using #4 listed in the PDF document. Try and fill in the blanks with your numbers and see what happens?
