So I just started using MMCD, and I am getting .8 at idle and a peak of 6 at WOT redline. Based on my calculations and guess that the scale is BAR, that translates roughly to 11psi and 87 psi....that sounds to me like I need a new bottom end (top end is fresh.) Any thoughts? Does anyone know what this motor usually runs at? At what psi does the light come on? How accurate is this gauge?
