    Check your revs...
    Max torque... 340 Nm at 2600
    Max Power...136kw is at 4750rpm

    So once you're above 2500rpm not much is going to happen all the time your foot is planted

    02 sensors?

    I had similar thing a while back.
    Cleaned MAF as you did, even bought a new one.
    Slight improvement with cleaned and new, but not much.
    Turned out to be failing 02 sensors.
    Changed them. Made a HUGE difference.

    Cheers.
