When you let off the throttle, you hear a woop woop woop. My 04 LB7 Duramax would do it if I was powerbraking and let off the throttle real fast.The duramax was loud. The powerstroke bark is real faint, but it's definatly there. Turbo bark is caused when the flow of air goes the wrong way. It puts the shaft in a bind and could break it.
