    Hi guys, got a boost problem with my vectra 2004,
    when i accelerate in any gear i can hear the boost build up and let off constantly as i go through the gear (like a quiet dump valve), any ideas?

    Check your boost pressure hose for any splits. What I'd check first.

    Do you mean the pipe between the intercooler and inlet & the pipe between the turbo and intercooler?

    Check the large hose that runs down the right hand side of your engine from the throttle body and also check the 2 small boost vacuum hoses at the front right corner of your engine.

    On the 2 small hoses at the front right, also check the elbow connections as these tend to perish and split.
