I have to ask why???
These trucks will NOT hurt them selves. ZERO reason to look at the pyro or anything else the truck doesn't show you.
I tow over 35k combined West Coast and don't give it a second thought. Pedal to the metal baby!!!
Now my 98 12V I had Boost and Pyro gauges. If I didn't I would have smoked #6.
That is what's nice about the modern diesels they are ready to tow right out of the box with NO MODS.
