Hey not sure you got your answer yet,but here it goes. Sounds like an injector getting compression past it.This happened with me around 1350 1500 rpms.It would shutter and miss,and blow black smoke.Only way to find out for sure is put a fuel pressure gauge on the return fuel line back to tank.You won't have much pressure on the return fuel line,maybe 10 to 15 ibs at most.When it starts chucking look at gauge and see if its spiking with pressure,if it is then you are getting compression past injector. For me I changed delta circuit senor and vpod. At this time its running good. But food for thought these 60 series 14L are touchy with this type of problem. Solution?? Don't use Lucas oil additives. these engines have a reason for cumming up soot with that oil additive. Also when you changed the sensor make sure there is no soot clogging the line. This sometimes is over looked. Hope my chicken scratch helped.

Why would a void and delta circuit sensor repair compression getting past injector?
