I don't think you are going to notice a performance increase after you rebuild your nozzles. I rebuilt mine after about 300k. Sure the engine is quieter, fuel economy appears to have gone up a bit and I'm glad I did it; but you aren't going to notice any huge performace gain. BTW, when I pop tested the old ones they were shot so if there was going to be a performace gain, I should have noticed.

You need to check other things first. Make sure your air filter is clean. Pull your tank screen, clean it and blow out your fuel lines. Change your fuel filters. Even run some diesel purge through the old nozzles. Do all of the simple cheap things first that are likely to zap your power rather than throwing money at new nozzles. I have nothing against new nozzles, I just don't think they are going to solve your problem.
