Hello, I would like to apologize for the long post! Okay so I'll start it off with what I have done to the truck so far. It is a 1998.5 2500 5-Speed 4x4 Cummins. A little under 900 maybe 1000 miles ago I have installed a new VP44, Airdog 100, OEM Cummins connector tubes, 7x.009 100hp injectors, and I also had to have my computer rebuilt because the throttle circuit was shorted out(I may also add that the truck used to prime for 3 seconds and it no longer does, I used to be able to access system function from a scanner and no longer can, The truck sounded ever so slightly different after I installed rebuilt ecm aswell). I have a few more things coming within the next 3 days including banjo washers for the bolt at the back of the head(I may also buy the Fuel Grommets at the return T soon aswell), BD Boost Fooler, and an Adjustable Turbo Elbow. There is also a programmer for sale that I may pick up aswell next week. But anyways now to my problem. I installed the new injection pump and airdog at the same time and then drove the truck for about 2 weeks and it sounded slightly different but ran fine.Then I decided to pull the trigger on some DFI 7x.009s . I installed them and the truck started up, smoke white for about 30-45 seconds and slowly went away and the "Air-Filled" idle started to go away too. The truck still had a rough idle after letting it sit for a while. So I got into contact with Chris and he sent another set out the next day. Boom the rough idle is gone. If I am in neutral and let the RPMs climb and then hold them at a certain spot the truck will shake quite a bit or whenever I accelerate hard the truck shakes quite a bit aswell. But the acceleration could be bad u-joint on front driveshaft maybe? If I give the truck more throttle there is an odd "miss" sound coming from the exhaust(not from the motor that I can hear anyways) The sound reminds me of an old non turbo 7.3. I ordered feeler guages and they will be here Monday and I will be adjusting my valves to see if that helps as they have never been adjust before. I know of two 2002 6-speed dodges that have 100hp and 150hp injectors and they do not sound like mine. Does anyone have an answer of how to fix it? I'm guessing maybe the tune in the computer is off and I just couldn't hear it with the smaller stock injectors or maybe the valves are opening slightly off and it is doing this or something?
