Commanded and actual angles are within a degree of each other for both banks under WOT.

Fuel pressure is good, I have an innovate gauge in cabin to keep tabs on that. Airflow to bank 2 drops, the MAF shows decreasing voltage and the AFR sensor starts to read rich.

Sounds like you have a boost leak. I would test it if you haven't already.
