I know some diesel rigs have a high idle feature from the factory. Has anyone added this to their 6.4 Hemi or heard of it being done? I guess you could always use a precisely cut stick but I'd like to install something a little more high tech lol. Basically I want to know if there's an aftermarket solution to accomplish this?

No, the idle may fluctuate 50 RPMs as the compressor cycles on and off but nothing like high idle. What are we trying to accomplish with the high idle in a gasser? Oil pressure worries? I own one, just wondering.

Bingo...for someone who lets the truck idle for hrs at a time I'd like to have the option to raise the idle a few hundred RPMs. I change the oil every 5000 miles or 100 hrs of idling but a high idle would help with that and while using my ecoflow alternator charger to recharge my batteries. I'm at 35k with 0 issues so that regiment has been working but I'd like to have the option.

I wonder what causes the RPM increase and if it could be enabled on a non-power wagon?

Low battery voltage causes the alternator controller to increase charging, which in turn causes the load on the engine to go up and it slightly raises the RPMs to accommodate the new load.
 
I only brought that up, because when I got my 2018 PW I thought that idle up would be nice considering how much winching I do. I looked hard at setting it up like it can be with the Diesel, but finally determined it was not going to happen. Or does the Dual Alternator package effect how the system works? Mine is dual. What I found on a typical single alternator vehicle is while it will increase idle as load increases, its too late to keep up with battery drain or not enough. Hense setting the throttle for those demanding loads would be helpful. However, I have not run into to much trouble with the duals.

I've spent over an hour winching at close to the max (Chevy dually with a slide in camper and a trailer stuck in the mud) and never had my battery drop noticeably. I also have the dual alternators. I wouldn't worry about it too much.
 
My worst recoveries were Heavy Equipment. Nothing like getting some heavy equipment stuck to ruin a few hours :D I do love them dual alternators for big jobs. When it does idle up for them, you know you are working!
