Idle refers to load and high and low to speed. When i set my tach which senses pulses in the alternator they said to calibrate the tach at high idle. I used a strobe tach on the crank while my wife had her foot on the floor board. Those who think a cummins is load driving should hear it with thier head two inches from the block at 2600 rpm!!
