I just installed an aftermarket boost gauge and under load (ie driving) it reads max 17psi. Is this right???

How do you think it pumps out 200lb ft and 112 bhp from a little 2.5 four.
It`s also the reason heads/gaskets let go more than occasionaly.

The new compound turbo charged C series Cat truck engines run up to 85psi in some applications, the run a water to air cooler followed by a air to air aftercooler.

Not quite. Factory spec for 200TDi 0.82 Bar (12psi) measured at wastegate. 300 Tdi is 1.05 Bar (15psi) - so slightly less than I said above.
