Confirm working on Dell XPS15 9550 (i5-6300HQ)
I can confirm this program is working on my Dell XPS15 9550 (i5-6300HQ) with the following configuration:

This device also works OK with the similar tool intel-undervolt and usually retains settings from Intel XTU on Windows even under Linux, in my experience.
With throttled enabled, I get geekbench4 scores of 4073/11110 (single/multi). Disabled (using balance_performance), I get 3928/10393. I only tested over two runs so the variability in the performance could be large from run to run, I do not know.
Actually, it appears that, at least on my Arch OS, the /sys/class/power_supply/AC*/online file is not created at boot IF booting from battery. Instead, /sys/class/power_supply/BAT0 is created, and throttled fails because of this. /sys/class/power_supply/AC*/online is created as soon as AC is plugged in.
Please check the testing branch. I've add two fallback mechanisms relying on upower.
Do you know what I need to change in the AUR pkgbuild to test the testing branch out? I guess only the URL?
Thanks. Seems to be working, I am getting No valid Sysfs_Power_Path found! Trying upower method #1. Maybe these warnings should be forwarded to systemd, so they are available in the logs.
