Those bosh plugs? they are platinums? well imo, they are crap, are they gapped?
stock fuel pressure is at 38-40, that should be fine, does it 'pop' when you accelerate? are you sure the plug wires are in the right order? even some of the best of us stanger's leave one off from time to time  check timing also with a light.
