    Default pulsing boost prob finally fixed!

    alright chaps,thought id post the fix to the annoying pulsing boost problem ive had for a while to help anyone out who's got the same prob.
    ive got the z19dth engine in my saab and for a while now ive been getting brief cuts in power on wot and under load,when boost kicks in it starts going on/off on/off in quick sussesion if you know what i mean,anyway after a shed load of searching on the prob and cleaning sensors and a lot of head scratching ive finally found out that it is a dodgy boost control valve/solenoid,my bro who's got the same engine in his astra let me borrow his to try out and it cured the prob straight away,after fitting his to my car it started boosting smooth with no pulsing just the way it should,hope this info helps.
