Hi to all.
Right i have a sapphire cosworth and there's a boost problem.
The car will not give me a proper boost but the hose from the actuator to the amal keeps getting blown off and the car will boost very very well.
Could it be the acuator at fault and if so is there a way off checking it . i.e movement

 

I know nothing about cosworth but i do know you do not want to drive with a pipe off your actuator as that runs massive boost and will kill your engine

Are the pipes on the amal valve round the right way,
