    Unhappy Astra coupe turbo sticking boost

    Hi all , need some help
    afte changing my blown vxr turbo that lasted me only a shooking. 8 months ! I sourced a mint standard unit. With less than a thous miles on it for£150.
    After fitting thou I have noticed the car some times sticks on boost. At 10 psi, at hard acceleration. The car. Should be running about 20 psi. And just over on over boost . And it still does most of the time . This norm happens in 2nd gear. However I have no prob when just chugging along and overboost
    . The car has a custom map , fmic , precat. , zorst , irridium plugs etc , dv

    Any suggestions , at first I though dodgy acctuatir but it's got loads of movement , the waste gate must be moving. To open allbthe other times.

    A sensor ? A solinoid ?

    Cheers dan
