Background
I've been trying to tune my 2008 300C (5.7L) for a stable idle.
Currently I'm fluctuating about 25 to 50 +/- rpm at idle (in/out of gear). The car has always been like this, I had CMR tunes in the past and am now trying HP tuners. If a 25 rpm range is normal, I understand, and it could just be a pet peeve of mine.
I've already gotten rid of a low-speed, choppy, partial-throttle, and better WOT response. I'm hoping there's a setting I'm missing or guidance from the forums.

I am currently waiting for a WB O2 to come in, but wanted to try to get my idle as stable as possible beforehand.
Anybody have some tips on stabilizing idles to a 5 to 10 +/- target range?
If you want to see my tune(s)/log(s) just ask.
