to find boost leak...

Look around the engine bay, pull the black cover above the DI and follow the small hoses looking for one that is disconnected. I have had this happen to me more than once and it only take 5-20 minutes to resolve.
If the hoses feel brittle, one may have a crack that is leaking (much harder to find.) If that is the case you may hear the air seeping out (hisssssss)while the engine is running.
Most the vacuum lines run:
- under black cover above DI
- along and behind 2-3 inch intake tube going to the throttle body. Intake tube runs from front of engine bay towards the back on the drivers side of the engine
- from the BPC down to wastegate and turbo. BPC is on passenger side of engine bay near the back of the headlight. It should have 3 hoses that run down under the engine
Hope this helps!
