I think if you are getting in the 9's on boost you do not have a fuel volume problem. that is the hardest spot to deliver fuel and you are getting plenty of it there. I have had these problems myself and part of it was the calibration in the fuel head. my calibration issues were because IA modified the head years ago. I'm guessing your head is fairly stock though. so if I'm reading this correctly you lean out before the warm up regulator will do boost enrichment, and then as soon as you go to boost via the warm up regulator it goes real rich.

I would suggest you plot your AFRs on a graph vs boost pressure and rpm.

My car is a convert 3.0 SC, but principally the same. 930 WUR, but no vac retard.
