heres a tip, turning the screw up inside the plate is only step 1, there is another screw on the pump to get it to smoke, that screw everyone tells you to turn up only affects how much fuel you get at peak torque and under a load, but going less than 1/4 turn will help for step 2. to get to the 2nd screw, go to the injector outlet lines where they are in a circle, in the center of that there is a fuel line going in to the pump, unscrew the line, and there is another allen screw inside there, turn that one in clockwise 1/8 to 3/16 of a turn, if you want go no more than 1/4 turn. It will smoke good now.

What should I do to fix this?

that sounds more like a personal problem than a truck problem. :evil:
