It sure could. Either way tho it prob bad, so change it out and see what it does.

Ok, well, i had the LBZ cp3 on the way and it somehow fell out of the box on its way here......:confused::rolleyes: I dunno if you saw the thread:D Oh, well. Ill pick another one up here soon. Im sure my cp3 is done for too. Can you explain how it would give me more lag and less boost if the fprv was faulty? Lose power? I still waxed some dodges 2nite:rofl: ill put the vids up.

That sux, I would go crazy if I got a empty box.

If the fuel is not at the correct pressure it wont atomize correctly and also you wont be getting the same amount per given PW. Fuel spools the turbo, to an extent....If I had to guess I would say this is your whole problem you have been having for a while, its just that it finally got bad enough to set a code.

Yea, your prob rite about it bein my prob. The thing that confuses me is that it still throws TONS of smoke but, still i have less boost and because of that my egts are crazy. It idles in park at 400deg when it used to be 250deg. Could it cause this too? Sorry for all the questions.

less fuel at lower pressure will usually smoke more than more fuel at higher pressure. Its no guarante but like I said, if I had to guess that would be it. Don't know when the higher egts at idel started but header wrap will make them read higher.
