[550L's]

I have a 2015 550xi, engine mods are as follows:
Stage 2 E30 BM3
Stage 2 XHP
Charge Pipes
******* DP's
Arm Front Mount Intakes
N63 Intake oil cooling valve
Lower temp thermostat
3.5 bar pre throttle TMAP's
NGK 97506 at 0.22" gap
Delphi Coils

Recently Replaced the following:
Pre throttle TMAP's
Plugs
Coils
All O2 sensors
Ran Liqui-Moly Fuel System Cleaner
Fixed boost leak with PCV

The car has occasional knock on data logs and cannot make target boost. It does not feel 100% normal when driving and feels slow. I recently took it to a shop and they said everything was fine, not burning any oil or coolant. There are no shadow codes and no CEL VIA ISTA.
Here are some data logs i got from today:
bootmod3 dot net/log?id=6256055ad10b435c47ba6fd9
bootmod3 dot net/log?id=62560518ae729b0653705bb6
bootmod3 dot net/log?id=62560518ae729b0653705bb6
bootmod3 dot net/log?id=6255e383c090c6511ab8d2b4

If anyone has any idea what it could be please let me know. I am out of ideas as to what it could be.

We don’t work with BootMod logs. And I don’t think most of us work with BM3 at all, and when we do, it’s purely back end with the JB4 controlling boost.
