The Hallman Pro Boost Controller is one of our favorites to use! Up to 60+ psi, it's been proven again and again to work! The valve is machined out of billet aluminum and stainless steel pieces, available in 6 anodized body colors. The Hallman Pro was designed to not require the use of a lock nut or any type or allen wrench to be able to adjust your boost. Simply turn the adjustment knob and it stays. The adjustment knob cannot be lost or come out of the valve. There is not a potential for overboosting since the adjustment knob cannot vibrate loose and come out.
