Inactive 30FF and O2 Sensor 2C7B

Getting these two codes through MHD after trying to pull a log from 3-6K RPM.

Wasn't throwing any code at all before I installed a LPFP Stage 2 today.

Mods:
Upgraded intercooler
All vacuum lines replaced
Pure600s
Chargepipe and BOV
LPFP Stage 2
Catless downpipes
Inlets/outlets
Boost solenoids were replaced not too long ago

Everything is basically new with the turbos etc.

Any idea what it may be? could it be the tune I'm on?
