Yea, most people say NOS and Propane are effectively the same for Diesels. The difference is, NOS can only be done at WOT, propane the turbo just needs to be spooled up.
Diesels run at wide open intake, so they are always very lean. More air makes the diesel burn better so that's why they get turbo'ed, then cold air has more O2, so that's why they run inter coolers. My 95 didn't come with a factory inter cooler, I want to add one though. The newer trucks with the intercooler are something like 525 ft-lbs factory, while mine is 450, but they also have a larger turbo, probably to offset the extra intake air volume in the system.
