MK6 GTI no boost, no codes and a very loud turbo whine.

Hi, so last week I was casually driving to work, not even really giving it throttle, but when I pressed the gas the car barely moved and it sounds like you can hear the turbo spooling up and down but not making it to the engine. The car is stage 2 and tuned by stratified. When I give it gas my boost gauge showed around -0.2, also I checked the diverter valve “ revision D” so can’t tear but oil just poored out, same story with the charge pipes which are ARM Motorsport TOP and Throttle pipes, all the charge pipe gaskets look good and fit snug. I haven’t driven the car much at all but no engine codes. I’ve looked at countless threads but no one has had the same problem with no boost and a very whiny turbo, so I decided to make my own. If anyone could help it would be greatly appreciated.
