    Default Boost problem, unsure what

    Driving home I put my foot down and the turbo kicks in a lot later then dies then kicks in again etc, the car has lost a lot of power and the just won't boost at all, no whine coming from the turbo, no smoke etc, anyone had the same problem? Happens throughout all gears.

    Don't go jumping to conclusions mate could be any of the above . I'd start with changing front and rear bcs and VAC box and take it from there
