What do your AFRs look like when you do a pull to redline? The ECU will go into open-loop mode which ignores the short term fuel trims (they should read 100% during this time).

Have a tune session planned but can't tune until I have this resolved.

my bank 2 will sit at 97, but my bank 1 will jump between 100 and 125.

at idle my AFR for bank 2 is around 14.7 and my bank 1 will jump around from 12s-16s.
