It could be so many things that can cause your car not boosting.
- Fuel cut - ECU is in low boost mode and prevent TVSV to open due to errors from knock sensor, intercooler level sensor, etc..) - Clogged cat - Stuck open wastegate - Bad turbo -------------------- _Gary

do a boost leak test to see where the leak is if there is one...gotta be a pretty big leak though if you have "no" boost. Other than that, maybe the turbo's gone.
