    fmu or not

    I have a ford 383 in a 1991 mustang, it has 36# injectors and its running off an accel gen 6. I am waiting to install a D1 making 12#'s of boost. It doesn't have a fmu. My question is can I get away with the 36s on that boost, or would I need a fmu, or do I need bigger injectors first. what would you reccomend 42s or 50s.
    Thanks Steve

    Using an FMU would only be crutch that would never run to its potential. A 50 pound would probably get the job done, but they may not be enough depending on how much boost your going to run.
