Tillix Boost control valve

The Tillix Valve is used to control the boost level in vacuum actuated turbo diesel vehicles. Often smoothing the turbocharges boost as well as giving the end user final say in how much boost is applied to the engine.
The valve only kit will only allow maximum boost adjustment. If you would like control of the spoolup rate of the turbocharger as well please look at the full kit that includes additional hardware to achieve this.
