    Turbo Pulsing under acceleration

    i have an 07' wrx, recently i had a blow off valve solenoid code pop up and randomly clear itself. My turbo started pulsing between 6-10 psi under about half throttle acceleration but maintains a constant 13 psi under heavy acceleration. Any known issues?

    what kind of boost control do you have? Is it a manual boost controller? They're known for causing "PTFB" situations. That stands for Partial Throttle Full Boost. That can give you a p0244 (wastegate solenoid out of range).

    It's also VERY common on 06-07 WRXs to get the P0244 if they have a catless exhaust that's not tuned for.

    Also in 4th gear if i get on the throttle hard it'll cut fuel around 5k rpm, could this be a related issue, And how would i check what kind of boost controller i have? im new to the subaru motor and turbo'd motors in general.
