The blower doesn't necessarily require more fuel alone, it requires more CFM than a similar naturally-aspirated motor.

Is this a pressure that you have seen on a gauge or are you saying that the regulator is set at 6 psi and you haven't really monitored the fuel pressure at the bowl entry?

None of what you have said would lead me to that assumption. Tee off at the carb inlet(s) and install a mechanical, liquid-filled 0-15 psi fuel pressure gauge. I'm thinkin' that what you're seein' at the regulator ain't what the needle and seat are seein'.

And by the way, what exactly does this mean? " the carbs seem to be overly wet"
