Question Correct Idle RPM

Was wondering what is the factory idle rpm of a 6.0L LQ9 motor?
Mine idles at 600 rpm's currently.

wasn't sure if 650 rpm's was the correct rpm idle. My vibrating idle goes away at a 650 rpm idle.
Anyone know the exact idle rpm?

The idle will stay the same with a Nelson tune. I just need to know what I should be idling at.

Maybe the 05 elec. fans on with the AC has something to do with it. Pretty big draw on the elec. system with them both on. I did switch out for a 145A alternator though.
