Spark plug gap/loss of power

Your fuel pressure is too high, that black smoke is a dead give away for running way too rich. Your base fuel pressure (with the vac line disconnected) should be set in the 30's and should increase the fp 1psi for each 1psi of boost. Running really rich like that will kill your power and your plugs.
