    Hi, I would like to confirm the requirements for a stage 3 ECU:
    Downpipe
    Exhaust
    Intake
    Intercooler
    Larger Radiator
    High Pressure Fuel Pump
    Low Pressure Fuel Pump
    Upgraded Coil Pack
    Blow-off Valve
    Larger Turbo
    TCU Software

    Any missing supporting?

    *Water/Methanol Injection is necessary or not?

    All depends on where/who is mapping the car.
    Generally
    Larger radiator. No
    LPFP. No
    Blow-off valve. No
    Upgraded Coils. No

    Plugs are a good change.
