Sounds familiar, i had many of the same symptoms and sounds last summer.. turned out to be broken (missing) fins
on the turbo.. while mine also made noise under load and acceleration, i really noticed a drop in highway trailer towing fuel mileage. new turbo and assorted hoses and gaskets fixed the problem.. mine is a 2016 and i think the new turbo performs better than the last one ever did.
