There was no knock during the event and my EBC recorded a 36 psi pressure spike which was triggering the "warn" function on the Blitz DSBC.

Yeah, this sounds like the the intake charge lighting off. This is actually the first time I've talked with someone that had the data log capability in place to see the pressure spike.
You're exactly right that increasing your base fuel pressure and leaning out a notch would increase timing.

My solution has been to use a 50/50 water-meth mix. You still get fantastic cooling and some extra fueling, but the mixture doesn't seem to be ignitable. Reading the old WWII research papers, this is the mixture that they found to yield the best knock suppression results.
