    when i come off the throttle, you can hear the turbo slowing down faster and a slight splutter, i've been told its back presure driving the turbo backwards.

    The exhaust is standard.

    i get this mate.
    go into 2nd gear and go to about 2500 rpm with the turbo boosting then bring ur foot half way off and it gives like a chatter.

    mine is loud as i have a bmc kit on and remap.

    dont worry im sure its normal.

    you should get an uprated exhaust system with a decat, then get it mapped again to suit the system, chuck a k&n panel filter in as well for good measure and then you'll notice a massive difference
