No. Did you only read my first post?
As of today I'm at 12:1 under boost. See graph. Assuming I don't run out of fuel it should stay around 12:1 at 10 lbs, carb meters air to fuel. Once you get the AFR right a good carb should keep it steady, at least at that throttle position.
The primaries are supposed to be about 10 sizes lower than the secondaries, because the PV on the primary side compensates about that much. With no PV, you should run equal size jets.
Going to screw with the PCVRs to get the boosted AFR a lil richer, then I'll tune down the primaries, and depending on the response I get after f'n with my PCVRs I might even jet down the secondaries.
As far as the O2 sensor, I just installed it the other day. It's brand new, and per mfr spec, I will only leave it in when tuning.
