    fuel upgrades for nitrous

    So I have been doing little research on running nitrous in my truck. I'm leaning towards a 100 dry shot.
    Can I go ahead and upgrade fuel pump and injectors before the nitrous. As funds are available buy a nitrous kit?
    Currently running 31lb injectors.
    Do I need to change maf?
    Stupid question! Will I need to have truck returned just for fuel upgrades? I know need tune with the nitrous.
    Thanks guys for any tips and advice

    Unless you have a flew fuel pump I would upgrade the pump for sure. AEM 320 is an awesome pick.

    The amount of power you gain from your nitrous system is directly proportional to the amount of the fuel you supply to the engine. There are two factors that determine fuel flow with a nitrous system: jet size and fuel pressure. When it comes to jet size, always follow the recommended jet combinations and settings laid out in the nitrous system instructions.
