Forgot to add: David (pretty sure it was David, I'm old) told me I should put my O2 sensor in a primary tube, for corrections from Idle & up.
I have since had mine on Patterson's dyno, with eight O2 sensors. I run mine in sequential mode, so I can correct each cylinder. Now, the sensor in one primary on each side should be fine. I had nearly a 5% spread between cylinders before. They are all very close to identical now.

After having run at all the tracks in our area, I log the first pass at each track now, never have had to touch it the last couple of years. Much simpler than running a carb.
