At a quick glance - and mentally converting PSI to kPA and/or inHG - this looks similar to what I ran last, twin-plugged. Car seems to drive nicely.

Out of interest, I tried twin-plug maps (at least off-boost portions of them) with much less advance. Those were much less responsive/fun.

My engine builders general advice was to focus less on preconceived ideas of what the motor "should" need, and instead watch how it responds in order to figure out what it actually "wants". That does seem to work.
