What parts were changed between 160hp dodge v. 190hp truck?

[Diesel]

So I see there are 190hp truck cummins in larger trucks yet our dodges had 160hp. I am sure the 190hp engine had a smaller exhaust turbo housing than the 21cm I have but what else?

Bosch 190's perhaps?

Maybe bigger injectors and turbo. The housing just moves the peak torque around.

The only accurate way to find out is get a Cummins print out of both CPL's and compare them item for item.
