11.8

Boost and air/fuel are not proportional. Just because you run more boost doesnt mean you need richer fuel ratios.

however you'll need to add a fuckton of fuel and advance spark until you hit paydirt. I'm at 11.5:1.

Could be part of the reason that the power is so low? Were you encountering detonation at leaner mixtures?
