manual boost controller
 

sorry to bother you guys but which way do you turn the valve to turn down the boost?

It depends which kind of boost controller you have...

the TurboXS brand mbc is counter clockwise to increase boost.

If you have the Home Depot style controller, you open the valve to decrease boost. That would mean turning the valve counter-clockwise.

If you open it all the way, and the boost is still too high, you may need to drill out the holes (in the valve) a little bit to get additional air flow thru the valve.
