My car has started boosting up to about 20psi even though the actuator is set at around 10psi!!
If the Amal valve fails can it bleed off more pressure to the metering head than it should? (Bit like a bleed valve) and cause this to happen?
Obviously i'm not driving it until its fixed!!

Also thinking either the pipe from the turbo to the Amal, or from the Amal to the Actuator is split/leaking!
Anyone know what size these pipes are so I can get some nice red silicone to replace them with?

Cheers!
