In stock form it should top out at about 18psi and on stock head bolts you are typically good up to about 45 psi. After that it get's kinda iffy. And the stock pressure may also be a few psi higher or lower also, every truck has it's own personality.

But also be aware that the stock turbo runs out of juice after about the 25psi mark. It will make more but your making more heat then power after that.

Check out this site, it tells you pretty much everything about stock Cummins engines. There are even quite a few theory of operations lurking around there too!


Ram Diesel Index

Auto's and Stick's also came with different turbos, with different wastegate settings.
