I've been able to hit 200 kPa. It runs pretty good with 7.0/3.7/0.5, but the CEL flashes once or twice around peak torque. I don't get any big backfiring or anything, it almost feels like the ignition only drops out for 1 or 2 cylinders for a brief moment and then it's gone. The wideband don't really twitch at all, it reads rich for just a split second. I'm going to try measuring what the stock ECU uses for dwell once I get my scope fixed, right now I'm looking more into the minimum discharge period, I think 0.5 may be too conserative.

Also, I've been really working on my spark advance table since I'm finished with the VE table for the most part... Note the aggressive area in the "spool-up" bins.
