just looked on the fourms, and i saw this: https://www.beamng.com/resources/6-0-powerstroke-turbo-diesel-engine.21279/updates
so far we have these that are complete:
-Exhaust Sounds
-Startup Sound
-Shutdown Sounds
-Engine Model
-Intake Models
-Fixed Shutoff Sound Looping
there are others that's in the update area.
this is the best that i could find
when i get on my dad's computer again, i will try this thing out. i have no idea what vehicles it works out on, but i think it works on the Gavril D-Series. good luck with it!
