That noise is bad. It's called reversal or barking depending on severity. Also that's a 24v and this is 3rd gen forum.

That's not the turbo. My 2nd gen makes that sound when you manually put it a gear and run the rpms up and let out. It's almost like the engine load running down.

Wierd. I had no idea. I just thought the 2nd gens got reversal easily.

Thats not a wastegate or a blow off valve or bark, it's just that particular turbo when you let off. B model CATS (3406b) sound like that in big trucks when straight piped too but the 3406e's don't.
