    Need help with transition from P/N/D idle

    I have a 2014 yukon denali 6.2 (same as 2013)
    It has a VVT stage 1 cam from Gwatney 212/224 .563 lift 113+8 lc
    Kooks headers & exhaust. Stock heads just cleaned up a bit. It's my tow vehicle.

    I've been working on a tune that a local shop did not finish due to a misfire (bad coil pack) at the time for a while now.
    Somewhere I've changed the idle transition between P/R/N/D
    It will flare up 200 rpms sometimes... Then other times when going to D from R or P/N is stumbles and dies (mostly when at op temps)

    Can someone look at what I may have done wrong...????
    Thank You

    I'm having no success in getting a drive log attached here.

    Your base setpoint idle rpm is too low for that cam try 800 rpm from 155* to 284* areas.

    Ok.. I'll try that ... I was wondering if my base idle airflow is ok... I've got it set to run best in PARK... but
    over the last month I've tweaked quite a few things
