    FAST 30397-8 39lb LS7 Style injector data for Gen 3 408

    I am having a hard time finding data on these injectors i need to tune my new 408 but i cant get anywhere because i know my injector data need to be changed but i dont know what is the correct data.
    Should i be using stock LS7 injector data???

    A file from anyone using these injectors would be greatly appreciated. I have looked through the forums already and came up with nothing useful so please dont bash me for asking.
    Thank you

    Here is my current tune with stock injector values Base408.hpt
