On a stock PWG N55, there doesn't seem to be much advantage. Logs look fairly clean, boost 14ish mid, 10psi up top with perhaps a bit more timing. IAT around 104 so today was hotter. Maybe it doesn't feel quite as good as the initial 93 stage 1 flash because of the higher air temps today (83f).
I just don't think there is much advantage on a tiny PWG that can't generate enough boost up top. On my E90 N54, an E30 mix would generate substantial gains - this one is sort of meh...
Theoretical question: Assuming equal timing and boost on a given car, will an E30 mix make more or less power than 93? I'm assuming it will make a little less...

I believe .022 is recommended, not .020 for 1 step colder plugs
