Had a friend few years back, his diesel coach with Cummins was low on power. Went to a few shops & each time they would work on the injector pump & give it more fuel. It got to a point it smoked quite a bit, pulled pretty good, but would run hot in the summer time.
Finely he had enough & carried it to a Cummins shop, come to find out the intake gasket was blown & loosing boost so no wonder the engine was low on power.
Boy when he got it fixed, you talk about a diesel coach would carry you for a ride, was like riding in a car or pickup it had the pump turned up so much. Later he took it back & had the pump turned down a bit to keep from melting the exhaust manifolds.
Probably wouldnt hurt, to get the injector pump checked out, could be something simple as the fuel stop(engine cut off) not opening up all the way & restricting fuel.
Any of you diesel folks, know how to make a Cummins or Cat diesel run like a Detroit.

Pull the engine stop about half way out, or until you feel the engine slowing down with your foot on the gas pedal flat on the floor & it will run just like a Detroit.
