imnot intirely sure how it works...

but unpluggin the amal halfs the boost...

dont think it reduces the boost at a certain rev mate think it only reduces boost if ACT's get too high or if it starts to dept.

i think the way to set em up is to get *half moon* on ur actuator wen u pull the arm over the pennys arm... then if the amal valve has no jets in i think it runs bout 5 psi...


then go from there with adjustin the jets to get ur boost u want...

think wen ppl have 2 stage boost contol is coz they put a manual over ride on the plug to the amal valve... hence halvin ur boost at the flick of a switch!



hope thats pretty accurate and helps!
