Are you referring to edges canned tunes, Gryphon canned tunes or custom tunes?

Default rough idle

I am using a Gryphon with custom tunes, a converted Edge.

My truck seems to have developed a similar issue as well. When it sits idle for a few seconds, it drops and "shakes" ever so slightly and then idles back up. This just started a week or 2 ago.

Rob, Clean your MassAirFlow Sensor first. I konw you're dumping a oil/gauze filter and that could be the problem. The oil will dirty up the MAF and cause rough idle issues. If that doesn't fix it dig deeper.
