    So your using the standard fuel pump and injectors from the 3.8 ecotec?
    what about standard tune?

    Why im asking is i have a powerdyne supercharger that i want to put on , but i need some super 6 injectors .
    But if your running then on the standard ones, i should be fine then haha

    I had a tune with the auto in it now its back to manual on a standard tune with it also runs well but def best off switching injectors now before tune
    it will run if you have a FMU hooked up i use 1 to 6 ratio, it will work well with a BD-11 on standard fuel system
