Make sure engine gets to operating temp so the DME stops makeing the fuel mix rich.

Here are some more stats, including temp - she's warming up. So we can eliminate that. It does appear that downstream Bank 2 has a bad connection.
Same info, one with raised RPMs.

Your 02S1 volt for B2 seems to varies the most compared with 02S1 for B1. The voltage drops from 0.67 v down to 0.05 v. Could be a bad 02 S1 sensor for B2 or because the voltage for 02S2 B2 doesn't seems to be changing the DME is assuming that the mixture is still rich so it continues to remove fuel from the mixture and that is why the fuel trim is so high. This is just base on a snapshot of the engine, the voltage should be varying constantly. If the volatge is not varying you could have a lazy 02 sensor.

I guess in short, with the age and supercharger - I should slate it to replace bank 2 up and down and ride.
Looks like $60 upstream and $90 downtstream on FCP with ye old lifetime warranty
