    VCDS Log Check - is it running OK

    Did a 4th gear log today whilst I had my laptop with me.
    I understand some of figures but could someone tell me if this log looks OK, should I be worried about anything.
    Appreciate the help, or if I need to run more logs with different groups do please let me know.

    I noticed that from 5000rpm upwards, does this mean a tired turbo?

    Maybe the request is just being a bit unrelastic, after all if it was just meeting boost then you would not be getting as much out of it as you wanted, this way I guess it's making as much as it can.
