Tuning question after heads and cam

[Lexicon]

As long as you degreed the cam correctly, the notches on the timing chain cam gear, you should be good. The black smoke seems to be an issue with the computer or something. I never had an issue with Black Smoke on two E-303 installs. We retarded the cam gear during the install, but that was because of my selection of a ford timing chain. I expect that you did the required reset of the computer and everything. The fuel pressure setting should not produce such results, but I could be wrong on your particular application. Cam overlap could be some the issue, but by no means am I an expert in this arena.
