How much HP am I down?

[Slowhawk]

Got the wifes car back and it is very safely tuned right now -12lbs of boost and A/F at .840.

The car feels dogish to me like it should at this level.Figuring it could run a 13.2 the way it sits.

The car is built for 18lbs on pump gas.What kind of power loss you think I'm at now on this tune?

I'd figure 12 PSI with ported heads would be around 16 PSI with stock heads. I'd guess you'd be down 60-80 HP from 18 psi.
