4psi sounds right from a standard actuator set up correctly. you acheive the higher boost from the amal valve bleeding off some of the air
check if your amal valve is clicking
when would it be clicking BTW? cos you cant really hear it when the engines running
The amal valve should click when you turn the ignition on. (just once)
