I would look at going with the XFC with Stage II, and just toss in larger injectors for stage one. Something like V6 injectors (GN Regal are like 30#/hr) would give enough, and then we can look at tricking the PCM into thinking it is at WOT anytime boost is present, which would trigger PE mode (drop MAP to 0 and WOT told to the PCM). This is very similar to what the Turbo carb'd 231's and 301's did. They boost referenced a valve that if boost was present, it killed the vacuum under the primary metering rods, so they went up and went to full enrichment.
