Alright Cleaning turbo didn't fix the problem. Guess I'm off to buy a ebp sensor tomorrow. With the ebp plugged in it reads a constant mid 30's psi. And truck will not boost. Unplugged it reads a constant -8.4. Then it'll boost but it's not right, kinda like all or nothing feeling. this leads me even more to believe the sensor is the problem. I know some strategies use an inferred number and some actually read it, guess my 05 needs the actual reading. I'll report back tomorrow.

And at idle it sounds like a v8 muscle car, no turbo sound at all like it has always had. The vgt% is 15% and likes to hang out there at idle or low rpms, absolutely will not build boost at low rpms, just a ridiculous amount of smoke. I guess in an effort to bring down back pressure that it thinks is not right.

This is all after installing warren 175/stock injectors which I know is not the problem, I got some coolant in the sensor and didn't get it all out and shorted it I guess, the tube is clean and free flowing. Absolutely ZERO problems with the truck before all this.

Any advice before I go buy a sensor?

yeah EBP goes down with VGT duty cycle so your PCM is opening the turbo to relieve back pressure (it's thinking stuck turbo but this is not the case). This opening of the turbo is what causes the major lag and smoke

So new ebp sensor should fix me you think?

Oh, ebp codes are the only ones that I have!

most likely. How does the pigtail look? It's the same pigtail the ICP sensor uses and they fall apart just as often
It all looks fine, none of it is brittle or anything. Nothing like the vgt plug that disintegrated when I pulled it off!

The brittleness is useually because of the greater heat endured by the VGT.

The turbo generates a lot of heat and the surrounding air gets hot trying to disipate it. As I understand it anyways.
