Bad injector?

My truck has been having some off and on symptoms of a bad injector. It felt like I was hitting bumps in the road at about 50mph once and every once in a while I can feel a miss while just cruising,Performs well when in to it. It looks like the Stock + from Warren diesel are the way to go. My question is I have to tow about 4-5 hours this wwekend and next weekend is this something I should get changed before hand? Or can it wait? The truck has no codes and runs very well otherwise. Has fresh 5w40 T6 with new fuel filters and I run archoil


Also what are the benefits of the stock+ injectors? Will I need my tuning updated?

Thanks!

Sounds like what mine was doing....
Why you shouldn't drive around with injector codes!

Could just be bad fuel. A bad injector will usually belch smoke (black and white) and stumble under acceleration.

Ok I did just get fuel not to long ago. The ficm voltage is constant 48.5 and I do have the blue fuel spring. The stumbling is very subtle and doesn't happen often. The main time being where it felt I went over a few rocks in the road. My CTS shows no codes and the truck doesn't smoke. I just don't want any breakdowns in the next few weekends. Should I just run it and monitor the best I can?

Also the truck just turned 52k miles. I only use it to tow so it sits the majority of the week

You still need to know what your fuel pressure is. Time for a sensor upgrade for the cts.

Ok looking at either getting the edge kit or the setup 2 stroker has. Looks like almost $500 for the edge and the adapter? That's with the strictly diesel adapter. I think the cts will be a cleaner install
