    Like every other one of your threads you need more info, also that turbo is crap so probably your issue.
    Never argue with an idiot, they'll bring you down to their level and beat you with experience.

    Over boost occurs because its an over-sized compressor wheel stuck into too small of a compressor housing - along with an undersized turbine.

    X2 on it being a low quality turbo, I would pass.

    The chra is crap and as they said the compressor housing isn't correctly matched to the turbine side. I've got one on my b5. After 10k the turbo seals blew out and I sent it to Tims turbos in Annandale VA for a rebuild. He put in a genuine borg Warner CHRA and clipped the turbine impeller to balance it out. $450 dollars later after initially spending $450 for it. Have had no problems since.
