My 96 hardly smokes at all. I dont want a lot but i want some more. The only thing have done to this truck is a 4 inch exhaust and gauges. I would like to do more to this truck. my next step is a cold air intake. but i have heard of turning up the injection pump how do i do this. thanks

Thanks that did it for me. I already had gauges too but do you suggest i get a fuel pressure gauge also? If so how do you install that?

 

A fuel pressure gauge is optional but comes in very handy for diagnostic purposes.

Here's how to do it> http://www.cumminsforum.com/forum/94...-12-valve.html
