They're not low pressure, NTC 350 cummins runs 18lbs of boost. The 400 is around 27lbs if I remember right.
Keep in mind that a 400 cummins can put out 800hp at the wheels reliably so overboost isn't going to harm the engine in the short term.
The turbos on those things are so finely tuned it's not even funny. Never really thought about a BoV or much when I was working on them.
