hey responses! thanks! I'll bring this back from the dead...
I pulled a few more logs and in one of my 3-4 logs my FP dropped to 8xx. Yes. triple digits woo! I was consistently spiking to 20+ even on partial throttle and overboosting, usually holding 19psi all the way through. long story short, I've since ordered itv22's to try and combat some of the KR (which have mysteriously not shown up yet (ordered on 5/19))...and did some ATR work with a guy on another forum.
My FP is still dipping to 15xx consistently in the so I'm on the list for new KMD internals (which are in QC phase right now, per KMD).
Boost hits 18 and tapers nicely.
Here's the last log I pulled after the reflash. Still have a lot of KR to deal with; I'm hoping the plugs will help but likely will need to be managed through ATR ultimately.
