First time posting, i recently decided to leave the large tuning companies and tune my own car just for accessibility and customization of my liking. For this was looking for advice on a few things and questions to be answered. Currently tuned for E85 and have trouble with the car starting sometimes, i notice it will sometimes stutter when starting but always turns over, have adjusted many parameters such as all of the rpm options for cold/warm/hot, additionally touched fuel base cold FFV, cold enrich decay, etc. and still struggle to find the permanent solution. Additionally on occasion when coming to a stop the rpms will dip into the 500s briefly, I've mostly fixed this issue and it does happen too often but just looking for some more refinement. Also looking to do some novelty tune testing just for the fun of learning how to do it. Below ill throw down a list of the things I'm looking for. Try to refrain on asking why id want to do some of these because i know some of you get salty when people do things you "wouldn't do to your own car". Tune attached below.
~Start up adjustments
~RPM dip when coming to a stop
~Removing/Raising P/N rev limiter
~Ghost cam
~Burbles
Edit- start up & rpm dip corrected.

I'm tuning basically the exact same setup right now and I'm having an issue where at idle the car is going into Target N mode and it starts surging and stalling at idle in drive with the A/C on. I'm leaning towards the issue being because of the extra load that the A/C is causing. Its almost as if it is messing with the idle to meet a certain torque number. This is my first time messing with a coyote, so I don't know what all of these torque management things are just yet. If you have any idea what could be causing it id really appreciate it. Here is my current tune and the log that the target N started in. It happens around 21 minutes and 30 seconds into the log.
