I installed an aftermarket powerflex RMM recently and notice that my idle is hovering just below 1k fully warmed up outside temp is in the 90s. When coasting in neutral, it drop to 750-800 with AC on. Once come to complete stop the idle goes back up again. It has 1400 miles and I changed the oil at the same time when install the RMM. The NVH is quite noticeable at idle.

I didn't keep track what the idle was like before.

Perfectly normal. Mine idles at 1000 when it's real hot out and the fan is in hyperdrive.

I believe the regular idle sits at around 750 - 850, I can't remember the exact number offhand. So that's totally normal what you're experiencing.
