Yes, without checking plugs I wouldn’t know where I am. I still like to have o2 sensor and vacuum gauge. When things start to stabilize on both I see that the direction I’m at is the right one.
I ended up having 13.4-13.6 afr in park and 14.2-14.5 in gear. It was all over the place when I started jumping from 14.0 to 16+ in gear…
