I'm using Exxon 93 octane because there aren't many other options during COVID since some places stopped carrying 93. I'm also using 8oz Boostane Professional to raise octane to 98-99ish every fillup.

Ugg, that is part of your problem. Fuel up with either BP or Shell. Exxon is terrible. Takes some logs again and see what you see. You may have some blowbye and need to install catch cans to solve it. That has happened before.
