You can vent but your car will still run like shit. It is not the gm maft that lets you vent, it is the translator. The Aeromotive regulator with gauge is an adjustable fuel pressure regulator with a gauge. I have the one at Buschurracing.com. They are nice to have when it comes to tuning.

I would go:
used safc - 200
used 550's - 200
walbro 255 (low pressure) - 100
cheap B&M regualator - 50
catback (used) - 300-350
offroad dp (used) - 200

You would also want a datalogger (100). You could hack your mas if you need to (free).
