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. 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 threaded top cap (screwing cap in increases boost, screwing cap out lowers boost) then tighten down the lock nut to lock it in place. Adjustable up to approximately 25psi with the supplied spring. Adding a stiffer spring or shimming the stock spring will increase the max boost available. 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. Has 1/4" (6mm) barbed inlet/outlet.
Available options include mounting bracket and silicone hose.
6mm ID hose fits tight but certainly needs clamped on to prevent it from popping off. 4mm ID hose is tight/stretches over and would not need a clamp. 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.
Installation: Bottom port (opposite of adjuster cap) 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).
