    I first installed a rising rate fuel pressure regulator valve; to my turbo charged 328i (M52 engine)
    To begin with i was running it on low boost on the standard ECU so the intention of using the rising rate regulator was to increase the flow of fuel into the cylinder, as the injector opening duration is obviously set up for the factory ECU settings.

    I'm now currently installing a VEMS standalone engine management system.

    Would I be best off keeping a static fuel pressure? and what pressure would it be best to set it at?
    Or would it be best to keep the rising rate fuel pressure?

    Does anyone have any recommendations...?

    fuel pressure you want will depend on the injectors you have and how much power you are after.
    I'd be ditching the rrfpr to simplify things
    Ask your tuner which he/she would prefer

    I'm running siemens 550cc injectors
    Aiming for close to 450 - 500bhp (with the VEMS system)
    Will be running a base MAP supplied by Gunni to begin with, then looking to get someone to live map it for me...
