Default vacuum leak?

So something around my turbo is acting up. I know it's not a blown turbo, because I can still boost to 20psi (but for some weird reason, it seems to be holding 18-19psi instead of 15-16 [&:]), so it's something around that general area. Whenever I take it to more than 10psi, I hear a squealing-whining noise, sort of like a mouse squeaking. I have trouble boosting at all past 10psi as quickly as I used to, and there's no more feeling in the turbo. It seems to just gradually accelerate, instead of exploding like it used to. (Okay, it's a K03, so it doesn't explode... but relative to what it's doing now, it sure felt a hell of a lot better). I don't think I'm losing boost pressure (as I can still hold what I normally hold, just the turbo sounds like Kemp's whiney voice) so what should I do to determine if I have anything wrong? I'm going to go outside in a couple of minutes and check all of my turbo outlet/wastegate connections and make sure there's no vacuum leak somewhere

But first, I need to sit here and enjoy this:



Chocolate-brownie fudge muffin with strawberry and blueberry ice cream, topped off generously with caramel-sundae sauce and whip cream.

Your best bet will probably be to add more whipped cream and a cherry.

Haha! Will do man.

I hope it's a torn outlet. That would explain my symptoms; and I hope it is because it'll make diagnosing it very easy!

If it was a torn outlet you would not be able to build any boost. Or not 20psi at least. It would all rush out. Remember right after we installed your FMIC and that one hose came off? Yeah it would be like that.

I still think you should check out the vacuum hose going to your wastegate or in that area.
