    With the MAF disconnected it runs MUCH smoother but still not perfect.
    Also feels alot smoother accelerating too - I'll give mine a clean and if that doesn't work (didn't last time) i'll have to source another replacement.

    Damn.

    Golf-loon - Do the audis have the ICM ? Is that the one that sits in the airbox on the golfs?

    Check MAF

    Check Ignition Module Thingy (connected to side of airbox)

    make sure your air hoses arent leaking MKIVs are prone to Boost/Vac leaks

    check your downpipe is bolted to turbo correctly

    check O2 sensor.
