    Hi please can someone tell me how to test the hoses after the throttle body, as far as I understand when doing a boost leak test this will only check up to throttle flap,or am I being daft?

    This might help - linky

    Not sure what you mean by the throttle body leaking air... When checking pressure, the test is between the point at which the air is injected into the system and the point where you plug the hole with a pressure gauge/plug whatsit.
