Ebp sensor cause boost problems?
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?
