I've just had the turbo studs replaced as they were too worn to tighten the manifold before. Manifold is now tight against the turbo and it doesnt sound like a tank anymore. The only problem is now sometimes when i hit full boost the needle goes all the way into the red then the engine sort of cuts out and lurches before running ok again. Sometimes the boost needle goes into the edge of the red and stays there and when that happens the car goes fine, but i never know when its going to overboost then lurch. it happened a couple of times before i had the turbo studs replaced, but its a lot worse now.
I have a little idea it could be the wastegate not opening sometimes, leading to it overboosting, does that sound right to you lot?
If so how do i go about sorting it. And if its not that...well anyway, any ideas would be appreciated.
thanks
