Ok so I have a 04 B6 1.8t and just over the past little bit I have started to notice a loud air noise when I hit the throttle hard. The car is basically stock the only after market parts I have is a Forge intake and a Forge DV splitter and a in car boost gauge that shows that its boosting like it should be but it feels like it is not going anywhere.
I replaced the turbo last year with a brand new stock K03s, I have taken my forge DV off and tried the stock one again still no difference. I have checked all my clamps and can't find anything loose.
The question is what else could be the problem?
The car drives fine as long as I don't boost. please throw me some ideas because I have run out of my own
