It starts (cold) and runs and drives fine...idles fine at 700 rpm and no part throttle hesitation. If I didn't have an AFR meter I wouldn't know the difference driving around town and freeway. I haven't got into WOT analysis. Getting part throttle AFRs out of the 12s and into the mid 13s is an issue. I'll find out today if I was barking up the wrong tree with the fuel pressure.
