BLMs say rich, but WBO2 and NBO2 and surging all say lean - what gives?

[dktool]

I just ignore the BLM data and use the WB as my guide.

I misspoke here, I meant " use the WB as a reference" being just to monitor what the CL fueling is doing and under all conditions (except P.E.) it runs at 14.7 regardless of what the BLM number is.
Is that odd ?

It's when I tune the V.E. to achieve a higher BLM number that it swings so lean that the drive-ability is gone.
