As said, I removed my EGR valve today and cleaned it. After 70k she NEEDED it. While under the hood, I noticed my boost gauge fitting had a small crack in the outer nut that goes on last (holds the plastic tube and slip nut in place) I had drove the truck this morning before I did the EGR and boost readings were the same as always. Before cleaning, if I REALLY laid into the throttle, I could get around 27~29 psi. After cleaning, driving the same way as before I am only seeing 20~23 psi. Anyone have a clue?
I checked the boost fitting to be sure it was tight and it was but I will be replacing the connector with a new one tomorrow. I started the truck and listened for any hissing and felt for any boost leaks at the EGR and the fitting and didn't notice any. (I could only get around 8~10 psi in park revving the engine) Hopefully its a busted gauge feed tube
