As stated in the title, I was wondering if anyone knew what it meant by the length of those lines on the transmission tuning screen. To help better explain what I mean is the lines that get shorter and longer as you change the ratios. I over heard a guy on the Mic say keep the lines straight across at the bottom end when talking about gears 3 - 5 (drag racing.) Also what does the lines have to do in relation to the dyno chart and power curve. Before when I tuned my transmission I simply kept a nice curve in the length of the lines and at a closer ratio. Thanks guys your help is greatly appreciated.
