Need help with MHD Log Interpretation

Hi,
I was hoping someone would be willing to help me interpret what's going on with these logs.
FBO E90 335i (stock turbos) 154k

All of a sudden I'm not getting boost, and then as I'm going up in the RPMs its like smacking a rat with a hot poker and I just take off like a rocket.

Super weird.

I checked over all the lines, clamps, etc
Did a smoke test, no leaks, and I had spare boost solenoids lying around and swapped them out as well just incase because I don't have a multi-meter thing.

I switched to Stage 0 for one log and switched to Stage 2 after another log
Stage 0 I get 30FF, Stage 2 I do not.
I did my best to replicate the drive for each log.

I do not know what I'm looking for in these logs so any help would be greatly appreciated on chasing down this "boost leak".

The only thing I ever checked with the tunes is Wastegate Rattle Fix and would set it to 0% for Less Rattle, and sport coolant because hot climate. (incase that matters)
No burble or 1M throttle, etc.

Stage 0

Stage 2

Willing to pull more logs later today if I messed something up with these, sorry.
I am already under the impression I need to replace the turbos but would like people smarter than me to take a gander.
