    2006 Cummins Speedo Calibration

    Hello,

    I have been trying to get my speedo corrected on my 2006 Cummins with 35" tires. I have changed the Pulses per mile as well as the Tire revolutions per mile using the formulas I have found on the forum. So far I haven't seen any change when I go out to compare the speedo to GPS. Am I missing something or doing something wrong?

    Thank you,
    Josh
