    pop crackle on decel is a rich decel with retarded timing. so if your DEFCO settings are enabled shut them down to allow fuel to run on decel.
    the ghost cam effect comes mostly from reducing the idle over/under speed effects. you can turn it off or just lessen its effect to get closer to your desired surge. chop tone comes from being able to audibly hear the firing events at slow rotation so sometimes you need to reduce the idle speed a bit to get them to do what you want.
    i should not that if the cams are stock or close to stock specs then this is likely not going to have drastic effects. If anything you may be able to get a slight surge out of it by reduction of said over/under speed settings.

    do you have a tune file to share and some specs on the heads and cam that are installed?
