    5.9 magnum/JTEC+/Dakota

    I was looking at my timing table and the range goes from 650-4800 rpm. That matches a stock 5.9 magnum idle and shift points. I have modded my 5.9 and it idles at 750 rpm and shift points are now 5500 rpm. I can open the rpm range (horizontal) scale, but I can't add to scale (like add 5200 and 5500 on the top of the scale). Should I rescale it by multiplying by 1.12. This will change the scale range to 728-5376 rpm?

    Note: Current tune was made with dyno runs.
