What's stock afr under boost?

Perfect stoichiometry is 14.7. Right? The o2 sensors sole job is to keep it there. I assume the o2 sensor is shooting for this value whether under boost or not.

Lots of folks on here are running 12.5 or so under boost. Is that the stock afr also? Or is that with the 02 disconnected and a modified wur?

Just trying to figure out what stock is... Are folks shooting for the lower afr as a safety measure, or is that how the stock system reacts?

Thanks
