RE: High exhaust back pressure
make sure your IMAP and other egr related sensors and piping are clean and/or have been replaced recently.

maybe pressurize the engine and CAC upand check it for boost and or egr circuit leaks.

maybe remove the DOC and DPF and have them baked, de-ashed, and flow tested for a few hundred bucks at a local stealers$it
