    Ghost cam is pretty easy to do. I've done it. Works good. but can't get how to make popping?
    I know, I have to do smth with dfco and decel timing. Timing is easy, but what about dfco setup for lt1?
    How about a write up on what you've done to acheive that.

    Idle stabilization timing advance and retard both to 15-20 degrees for ghost cam
    Closed tps timing above 1200rpm to 0-10 degrees on ur taste. But i dont like it. It is just a few BANGS instead of popping, so it is required to play aroud DFCO. Im afraid of my muffler explosion. Need somebodys advice.
