Weber IDA Rich at WOT Options

[Tbrown4x4]

OK guys. I thought I had grasp on the air corrector jet function, but my wideband is confusing me. Everything seems to be within acceptable values (12.5 - 13.8 or so) in most drive cycles except WOT.

Example: Cruising 60 mph at 3200 RPM and floor it, AFR drops to 10.3 to 11.1 and stays there as long as my foot stays buried. Or, pulling a long hill in 5th with the pedal floored. Same numbers. Actually pulls cleanly with no audible pinging.

I always thought the air corrector jet was for high rpm mixture control, like cruising at 7000 rpm. The bubbles slow the fuel flow so you don't get progressively rich running at high air flows.

In my mind, from 3000 rpm with a WOT, the air flow isn't high enough to bring the air corrector into play until the engine revs catch up with your right foot.

Am I looking at this the wrong way? And would a larger air corrector lean out the WOT mixture?

BTW, I have 40 IDAs, 200 AC, 130 mains, 28mm vents, 50 (or 55) idles.
