Pressure Relief Valve. This valve determines the pressure in the fuel rail. The 'cracking pressure' of your fuel rail return valve is the point at which the valve opens and allows fuel to exit the fuel rail.

Because this valve has a higher cracking pressure than the standard 2.0T valve, you will get a higher rail pressure and therefore more fuel in the fuel rail. More fuel means more power.

This is a great upgrade for your fuel system as it will work with the standard injectors and also with upgraded injector and HPFPs. You should also consider upgrading your fuel pressure sensor so it can accurately read the higher rail pressure.

Use this for stage 2.5 tuning with HPFP upgrades on EA113 etc
