EBPS issue...never ending
Deleted EGR and DPF. Been going through this forum for at least a month and can't seem to find any current answers or relavant answers. The EBPS and the tube keep clogging on my truck. I have replaced the sensor twice and the tube was replaced last fall. Is their a delete for this sensor? If so, where can I find it and will it do any harm? And if this has been answered currently, please point out the right forum. As a follow up, I have replaced the tube, replaced the sensor and replaced the wire harness and it's still throwing a code and I am getting a strange whistle I have never heard before.

Crawl under the truck and get a good look at the exhaust manifold. Look to see if the exhaust bolts are missing. The whistle you describe is somewhat common on these trucks when the exhaust manifold bolts break and the exhaust gasket blows out. That will also explain your pressure problems. You didn't mention what codes they are so it would make sense that a low pressure would be detected with a blown exhaust manifold gasket.
FWIW, I'm hoping it isn't for your sake. Replacing those bolts is a major project. I did it with the engine on the floor and drilling out the old bolts and re-tapping new threads was a pain then.
