    5.7 tbi - larger cam tune advice needed

    looking for any input on tuning info to make this thing not run rich and stall at idle---
    car was a 5.0 tbi firebird---
    installed a 350 with minor head work, 10-1 compression and a decent cam
    .470 lift - 275/285 and 110 lobe separation..

    I have antt bins and axkt bins -- is there a few small changes I can do to these bins to help the idle--- its way rich --
    and I noticed these bins have base timing at zero ???? I usually run at 10*--
    any advice appreciated-- or does anyone have a bin I could start with and modify ??? thanks- steve

    moates -all in one - tunerpro - 27sf512 chips,,, everything burns fine and reads fine,,,
    I saved the bins from my chips and have been trying to alter them a little at a time,,,
    just this thing runs so rich it stalls--- if I could clear that up it would be helpful- thanks
