I have a slight fluctuation in the RPMs when the car is moving in neutral. I have changed the following settings (See attachment) with the addition of setting the "IAT Temp Based" to 704. I assume with the IAT's dropping with acceleration and increasing with throttle decrease that those should be set even. Am I on track to correcting the issue?

It's a little hard to know for sure without maybe a log file to see the issue. What you're looking for is what is changing that could be causing your issue. I'd expect the IAt based trims should be pretty consistent and smooth but by the same token I'd be a little surprised if you're seeing massive swings in IAT at a rolling idle that are causing your issue.
Thank you Andre,
Log file attached if you are interested. No pressure as I don't expect you to solve my issue, but presenting this as more of an opportunity to share experience to gain knowledge. After looking at the AFR it may acually need a little more fuel at idle. The cam has a pretty wide LSA but does have some duration that could lend to more effort in tunig the idle.
