Injector issues. new nozzles or new injectors?

[tbrell]

I have an 06 5.9l with 120,xxx miles on it. Running a Superchips programmer on eco, have airaid intake and 5 inch straight. I have been thinking for about 5 months now that I am beginning to have injector issues. Now, I'm SURE I have issues.

MPG is dropping, longer starts, white smoke at start up. I can tell that there is somewhat of a miss or weak fire on one or more cyl.

Now what do I do? Can I just replace the nozzles with some 50-70HP and have them flow tested, or will I have to change the entire injector or injectors?

I'm on a small budget, so what's my best bet here?

can someone just give me some names of some professionals I can call and speak with? After some reading I'm not sure I wanna risk trying to do any injector work(other than r&r) on my own...I'm in St. Louis, MO, willing to ship.

nozzles will be cheper than complete injectors...cal Exergy, Industrial Injection, T&C Diesel, and/or Motorsports (Wicked) Diesel. Any and all should help out with anything you need.
