Depends on the many ways to tune the truck.
And the fuel flow; bigger fuel lines, fuel banjos, pressure.
Along with the air flow restrictions; intake filter, turbo, boost tubes, inter-cooler, intake manifold(gogodiesel), exhaust.
The stock system can even support 155cc inj, if it can, some stock fuel systems are not able to because of age, maintenance, fuel restrictions.
If the stock fuel system was worked(list above) on to eliminate flow restrictions, it can do very well with HP numbers.
