does it pull well above 1500 rpm? or do you have breakup or a regular miss past 2000 rpm?

How many miles on those injectors?

Most of the time when injectors get over 150k on them they are pretty much done for.

93 W350 w/duals, fuel pin turned, 6X.018" injectors, 4" exhaust, 3" air intake horn, HX40/16, G56 /SBC Con-OFE, 307's axles' 2" skyjacker lift, B&W flatbed

High on the trouble shooting tree is the injection pump, if there is not a change that is confined to 1 injector when the injection lines are cracked loose. If it has been run a ways that might be 2.

Double check by doing it agin above 1500 rpm, the change should be the same for all injectors.

If 1 or 2 injectors show no change then service the injectors, if all 6 are close to the same do the pump.
