    Boost Pressure Lose

    Hi all, I have searched on the forum but didn't quite find the answer.

    I have a MY02 S3 with BAM engine. The boost pressure now is stayed at 0.8 to 0.9 bar. Some of the posts indicated that the pressure on the BAM should be 1.1 to 1.2 bar. I just got the DV replaced with a APR R1 but doesn't help. I would like to see what is the probable causes of the pressure lose?

    The car seems pulls fine but just not as quick. No obvious hissing sound heard during acceleration though.

    i think 1.1 to 1.2 bar are the remmapped engines, check those little vacuum hoses under the manifold they split and cause boost loss, and pipe to the dv.

    I always thought standard boost was around 1BAR, with remapped cars seeing 1.4-1.6BAR boost.
