Hi, i have a zed twinturbo import and just wondered how do you know if the turbo's are good and boosting well. the car has 62k on the clock. can anyone help thanks

Although the standard boost gauge is not great it would still give you an indication whether the turbos were boosting properly when you are accelerating. A sign that the turbo seals may be worn is the appearance of grey/blue smoke from the exhaust when hot and on tickover.
