Don’t diesel trucks and cars bark every time you get out of it to some extent? Gas turbo cars and trucks all have one thing that diesel cars and trucks don't have throttle blades (except for new trucks that have them for emissions).

when a gas car or truck with a turbo closes its throttle, the engine goes into vacuum which sends a single via vacuum hose to the blow off valve which releases the built up turbo presser to keep it from surging back ageist the turbo and stalling it.

So if your truck dose not have throttle blades or a blow off valve then every time you’re under load and get out of the throttle (pulling a trailer up a hill and some jackass cuts you off) the pressure will surge back to the turbo to some extent. So you would think that the factory would build accordingly?

I might be wrong but I think that’s how it works.
