    Need help with inconsistent start issue on Turbo Cammed 6.0 on P59 PCM 3bar OS

    I don't have much experience with the drive by wire stuff, have tuned prolly 50 cammed drive by cable cars and I cant seem to get the hang of getting these ETC cammed cars to idle like I want. Any help is appreciated.

    When you go to start the car itll run for about 2 seconds and die on the 3rd or 4rd attempt itll fire up and hold idle, then you can shut the car off and turn it right back on and it will fire up just perfect, shut it of let it sit for 20 minutes back to hard starting, I don't understand whats making it so inconsistent on starting.

    Details on build.
    04 model SBE 6.0
    317 heads
    comp cams 236/236 620/620 114 turbo cam
    twin VS racing 76mm turbos
    holley high ram intake

    Any help is appreciated thanks guys
