I'm not an injector expert but you can use stage 1 but it has to be splitshots as for the rest of your questions,how many miles on your truck.It would be nice to change all of that since your in there but i did mine with only 80,000 miles so i just left it in there.

"True" stage 1 injectors will require custom tuning to run properly. Edit: Don't waste your time staying with split-shot injectors. If you're going to do anything with the injectors, get singles.

Stage 1 single shots will need a PCM flash because it is now programmed for split shots.
Check cups for leaks when the injectors are out. Injector Cup Diagnosing
Thoroughly check the UVCH for Burned Center Pin and good connections. Quarter Mod for Loose UVCH
Edit: You should invest in a least an EGT gauge because the stage 1s may very well cause higher exhaust temps when you put your foot into it or when towing.
