Take it you have a new age STI then?
Limp mode.
Dealer to reset your ecu and check the avcr is working correctly.

sounds like its overboosted ect.. got knock and went into limp

 

it can't go into limp mode he has an AVCR fitted

I presume there is an issue with the wiring to or plumbing to the AVCR map sensor or 3port solenoid in the engine bay. Or the map sensor vac hose has come off
