This is our premium manual boost controller kit. Simple to use manual boost controller aka boost valve. Increases torque even at stock boost level by creating faster boost response so the turbo reaches max boost at a lower rpm.
The innovative design of the valve incorporates some great new features not currently available on any other manual boost controller. This boost valve is designed to not require the use of a lock nut or any type or allen wrench to adjust your boost. Simply turn the adjustment knob and it stays where you set it. Another great feature is the fact that the adjustment knob cannot be lost or come out of the valve, unlike other boost valve designs. Simply put, there is not a potential for unexpected overboosting since the adjustment knob cannot vibrate loose and come out.
Simply install between your boost pressure source and your wastegate/wastegate actuator. The side port goes to the gate/actuator and the bottom port goes to the compressor outlet or other boost source. Then simply dial in your boost pressure by turning the adjustment knob (screwing knob in increases boost, screwing cap out lowers boost). Adjustable up to approximately 20-40psi with the supplied springs. Installing a stiffer spring will increase the max boost available but also limits how low you can go (minimum boost).
Warning: Increasing boost can be dangerous for your engine. Be sure you have sufficient supporting mods, fuel flow, etc. to support the higher boost pressure or engine damage will occur. We are not responsible for damages.

6mm ID hose fits tight but certainly needs clamped on to prevent it from popping off in high boost applications. 4mm ID hose is tight/stretches over and would not need a clamp but it takes some work to get it on the barb fittings. So measure the port you plan to connect it to on the vacuum tree or turbo outlet and measure ports you may also connect to the same hose (like a boost controller) to determine which size you'd rather use so you don't have to adapt to different sizes.
Bottom port (opposite of adjuster knob) connects to a boost source (nipple on outlet port of turbo, or directly to vacuum tree). Side port goes to wastegate actuator (for external wastegate, use port closest to where the wastegate bolts to the header and leave the port on the end of the wastegate open to atmosphere, not capped).
To install a different spring, remove bottom port and remove ball, then screw in adjuster knob to push spring out far enough to pull it out. Reverse these steps to install new spring.
