FCD installed, dynoed again...
 
air/fuel did lean out some finally, but after 3600 it never went over 11.4:1. it only sunk below 10:1 at one small point.

10.5 PSI (up from 9.25 the other dyno time) of boost. we did it on the fly after hours and i set the boost level.

197.4 whp, 204.3 tq. for only roughly a pound and a half of boost, thats prettygood. i think that the FCD leaning it out some helped too.

i think a haltech will be in order soon, but adding another 0.5 PSI and busting 200 on pump gas will be fun. :) we heard no detonation, the A/F was great. i am tempted to drop in a gallon of toluene and see if 13 PSI is reachable. thank god for dynos!

the fcd doesnt lean out AFR's.....all it does is limit MAF voltage. JoeP sells a FPR (fuel pressure reducer) that will help lean it out.

scan those dyno's I wanna see the numbers.
