So I just got done replacing my injectors. Now I'm having studdering at 2500-3000 RPMs and have codes for "Charge Air Cooler Temperature Sensor Circuit High" and "Turbocharger/Supercharger "A" Underboost Condition" Anyone have any solutions? Thanks

Hmmmm, weird. I replaced all of mine, but didn't have that come up. Did you register the injectors and re-do the adaptations? Did you run ISTA D? Maybe 1 or 2 of the injector connectors isn't seated making contact not shooting fuel?

No, I don't have ISTA, do I need to? I swapped #1 like 6 months ago and didn't have an issue

So let me get this straight...you swapped an injector and your getting a boost code and a maf code?
You sure they are connected? I sure don't think they are... if you swapped the injector yesterday, I would check connections on everything you took off.... Its a good place to start.. keep it simple.. an injector code and boost codes are two completely different issues...and you are getting boost codes... You left something off or not connected right...
Also did you code your injector? I am guessing not..

What problem(s) were you having before you replaced the injectors?
Did you do something in addition to replacing injectors?

[natefank]

So the codes cleared up, I think it was cuz somehow my boost line for my WM got disconnected.
The reasons I replaced my injectors was because I was getting injector codes and stubbling at around 1200 rpm and idle

the injector numbs must be stored in DDE after swapping or replacing.
