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 and reduces the fuel flow through the fuel return system.
It eliminates potential low fuel rail pressure DTC codes P1093 or P0087 (low fuel rail pressure during power enrichment) that are caused by insufficient pressure relief valve spring pressure opening, returning fuel to the fuel tank.
