What would cause idle to fluctuate in park?

When the car warms up the idle in park goes up and down. If I switch her to drive within 2 seconds it evens out. Is that tune related or something else?

Running idle airflow in park isn't tuned properly, when you drop it in Drive the load and transmission dampen the pulses. Any decent tuner can address this.

your car looks very sharp in the white widebody. the flares blend in with the lighter color. i used to tune raf on my old pontiac g8.

Thanks! And I believe FCA uses the terms derivative and expected under the idle airflow section of the tune. I'll have to confirm later tonight.
