Its an analog gauge so who knows how 'off' it can be but seems to be working perfectly to me.

Log's suggest the tune is dialed in, if anything slightly on the rich side (to be expected). Once the bumper went back on everything quieted down significantly. You can hear everything, but the exhaust overpowers it a bit...anyway - more updates later on. Still here at work.
