    Any more information Goz?.... Are you running a standard turbo or have you replaced it with a VXR Unit?. Have you checked the actuator to see if it is catching and sticking open. The symptoms can be caused by a number of potential issues. More info may help people to give a more accurate response.

    Boosting to 1bar on a standard map seems to high to me.. out of interest how is your actuator set up?.. How many threads do you have showing?

    There's about 7 threads showing yeah it's a standard map it's only started todo it recently ! It's like it can't read the pressure or something which makes me think it's eaithrt the front boost sensor it the map sensor as iv had 1106 code up a couple off times I think that's the one for mao sensor/actuator?

    Usual set-up only has 3-4 threads showing, could be causing the issue as your turbo does sound like it's boosting higher than what it should!

    Right when I put it down to 4 or so threads I wasn't getting any over boost at all it took a little longer to build the boost up and only went to 0.5bar but it's like it's spluttering 2/3 times on boost ??

    Maybe you are getting the overboost, but it doesn't feel like it due to the fact the actuator has been set fairly high?!....

    Have you checked for any fault codes on your car??
