It coud be the turbo (not adjustable). Have you checked closely for vacuum leaks?

You could have a sticking throttle plate or the electronic throttle could befailing already. Usually with generic scanners codes will not pop up in the engine control module. The throttle is cover under the extended warranty 10 years from date of delivery or 200k miles wich ever comes first. Call Volvo and give them your VIN # to see if you are still covered and if you are have them diagnose the vehicle to see if it is the throttle failling.
