I feel like there are two issues here.

1. There is a knock/misfire/cackle in the engine that seems to get better as it warms up. Or, does it just sound like a PSD?

2. The turbo now sounds more breathy than a tight whine (on spool up, the dump afterwards is just more noticeable). Or, am I again just hearing new "normal" sounds?

So, does anyone hear anything I'm talking about in the clips?

Well I cant say for sure but it sounds odd to me. Dont know if its just the video but it seems like you should be able to hear the turbo more. And the cackle seems too loud. What mods do you have?

Someone that knows will chime in soon.

Edit: Never mind I saw your mods in your sig.
