The Release Valve Shim Kit increases the pressure needed to "pop-off" the pressure relief valve (PRV). This means that the available fuel rail pressure remains high, as requested by the engine computer during full-throttle driving. Reduces the fuel flow through the fuel return system due to an age-weakened spring.
