I believe all BRZs use the same flash config, since they’re all 1280kb 0x0-140000, etc. but my...

Does it sound like a tin can resonating at 4600-5100rpm, like the cylinder is hollow and echoing suddenly, and then go away?

S20G port injection ratio table

That FA24 graph reminds me of S20G's super fancy port injection table, which is way more complicated than S10C or U01A, so here's that. Different PI thresholds for this one - 10.0/75.0%, 6400rpm,...
