Boost controller problem
I have a hallman pro rx or what not manual boost controller and I can't seem to get less than 12 psi. I turn the thing down all the way and i still is wayyy over 10. anyone have any suggestions?

the hallman is a manual spring ceramic ball type controller. . what i mean by turning it down is reducing the tension on the spring to the lowest it can go. this is the same type of controller found in daiman's boost controller setup

with the light spring you should be able to range from 7 - X psi. With the hard spring you will not be able to go low enough if you are looking for 10 psi. keep the light spring and check the lines for leaks. basically look for anything that could cause the wastegate or Hallman to see less pressure than it should. are you still using your stock control solenoid with the manual controller?
I had the same problem with mine at first...it took forever to figure out because I thought my lines were good so I ruled them out. The manual controller cannot control anything if there is a leak (tiny crack, slit, hole) in the lines connecting it to the actuators and solenoid(if you kept it).
hope that helps.

hmmm refering back to my old post.. anyone notice that tiny machined hole in their hallman boost controller? i was wondering if anyone blocked this hole? what purpose does it serve? the only thing i can thing of is that it causes and automatic increase in boost once u install it..

If it were not there, the pressure that passed thru the controller would stay in the actuator (the controller would act like a check valve), lowering boost even when it was not necessary once the controller supplied pressure to the actuator.
If the pressure after the controller can't bleed off, it would lock the actuator (WG or PC, whichever it is connected to) in its actuated position and screw up the boost.
