Swaping vac ports on the dizzy won't make any difference when on boost. Both ports connect to the throttle body just in different locations, above and below the throttle plate.

Jim getting too much fuel on boost is not a typical situation, they can choke on the midrange of a stock engine with a failing WUR. This engine is modified so I would expect it to go lean. Good point on the AFR gage, great tool needed in this situation to help see what's going on.
