Engine surge/Feul pump?

I have a late 01 but title says 02 Dodge 3500 dually with a manual transmission and i noticed at idle and also when im driving the enigne rpm is not constant it jumps about 50-100 rpm u can see it in the tach. Is this a fuel pump issue or am i missing something else? This is the first dodge i have had converted from a powerstroke.[duhhh]

I would look hard at the APPS sensor. it can cause these symptoms. if so get the Timbo apps. Much better than OEM. You can find it listed on here a lot.
