AFR guage

Put the bung on inside of passenger side of the header. Ran it today and all seems well, installation-wise.
I'm a bit rich at idle. Don't know about WOT yet. Need to have some room when you're just stomping damn near 600 horses.

It was my first ride since the engine was on the dyno, but it seems easy to get transfixed on the gauge . I'm definitely going to need a passenger when I start REALLY checking AFR through the whole RPM range.
