On my dyno I normally shoot for 12.0 to 12:50(at wot). Most all of my dyno pulls are on turbocharged cars. BTW are you using oxygenated winter fuel ? Here in New York thats what you get at the pumps until spring time. That will directly affect the O2 readings on the dyno`s exhaust analyzer giving you those readings.
Also make absolute sure that no uncalibrated air is coming into the engine(all intake air must pass through the mass air meter). Check your idle valve for this. Does the engine run and respond just as it would if still in the 993 it came from ? Chances are you have nothing wrong with your a/f ratio. But its worth looking into and you could possibly find a few more ponies in that torque monster.
