    I noticed in that thread you used mph for speed will it work the same with kmh for speed values??

    Won?t make a difference. Just click the units till you km/h and do the same process with the value it shows you when the unit km/h is selected.

    Just as an FYI, that stock value given of 251 when mpg is selected is what?s in the calibration in the older model years, the newer 5.9 is as I said, 654. But doesn?t really make a difference in the end.

    This doesn’t do anything on my 07 5.9. I have even tried multiplying by like extreme numbers 0.8 times everything and it doesn’t change my Speedo at all.
