    Default First startup after turbo build- won't idle

    Hi guys, I need a little help. I'm trying to get my car to idle and not having much luck. I'm runing cos3, 5.7, 80lb injectors, vacuum referenced regulator, twin turbo, Speed density, etc.

    It starts up then dies within a few seconds. Pushing on the throttle just makes it happen faster. I jacked the fuel pressure way up and it acted better, ran longer etc.

    ****UPDATE**** I ended up changing the IFR # to a lower value and it is much better. Runs and idles now.

    Thanks,
    Frank
