Not sure what Cummins you have but I'd trade my first born for 35 lb of boost :)
Loosing boost usually indicates a hole or opening in the turbo charged air. My boost declined on a recent trip and there was/is a small hose, about an inch and a quarter diameter under the intake manifold that runs from the manifold to the compressor. Easy fix. Also the clamps where any hose is connected to the components in the charged air.
Your being able to get full boost at times would indicate that there is something else causing the problem and not a charged air leakage. Let us know the final diagnosis.
