    For the guys running stage 2, is the factory hpfp enough or did you upgrade. My car just will not give me a break! After fixing the low boost problem now im having low fuel pressure!!

    Are you getting problems with the injectors because of the hpfp?

    I know that hpfp’s can fail also cause low fuel pressure. Have you got vcds or obdeleven?

    You need to upgrade the HPFP internals, I have Autotech upgrade.
