This all looks amazing! Only thing I immediately see is via IPG, Core Min does not reach 0.7 as it did before:

Excellent work. Thank you!Yes, that's an intended design. I configured the min clock speed to be to 1200 instead of 700. Slightly higher battery consumption but better performance.
If you prefer a lower CPU floor, you can easily re-configure it using one-key-cpufriend.
Also sidenote, I've been experimenting with MBP16,3 but have had issues with patching the GPU framebuffer (as the card is an Iris 645). Hopefully will find a working combination soon and post an update...
Also, one-key-cpufriend now supports the MBP16,3 board-id.Yes, that's an intended design. I configured the min clock speed to be to 1200 instead of 700. Slightly higher battery consumption but better performance.

I tried and I can boot in Recovery without any issue with my EFI and with yours. I proceeded repairing the disk. If I try to boot with your EFI as-is I experience the same problem. I've tried deleting the 2 CPUFriend kexts and i removed the entries under Kernel->add in config.plist, but the problem persist. I even tried turning DummyCpuPowerManagement on, still nothing changed. Do I need to change anything else in the config.plist in order not to use custom power management?Never seen this on Big Sur. Boot to recovery, see if you get the same freeze. If you're good, try and repair the disk.
If symptoms still persist, you've probably got the wrong CPUFriend setup. Remove it (or try using my setup a few posts back without cpufriend) and see if you get any different results.
Right on cue. Here's the optimised configuration for 8550U 16GB QHD+ with NVMe drives.
For additional optimisation, change these UEFI parameters - but note that you will need to fine-tune these to suit your own specific CPU variant, as well as your current cooling strategy.

Please report back with performance scores.
Enjoy
I solved it, mainly thanks to another forum user. My main problem was the iGPU configuration. I changed AAPL,ig-platformid value and the device-id in order to match the Intel Iris Plus 640 and it worked! This table is not for some reason listed in the main guide and the values reported for Kaby Lake I was using was not correct.Never seen this on Big Sur.

Yep, OC documentation is way better than Clover's, but still quite a mess sometimes. Btw, as I can't find any reference, did you manage to get Handoff working? Mine kinda works, meaning that sometimes it does what it should, but most of the times it fails (ex. Safari showing in the dock but then not loading any page). I can't find guides on this topicThat page is full of bugs, unfortunately. For example the device-id for UHD620 is incorrectly swapped resulting in the 8550u series not being able to work with that config. Took me ages to figure out that one...
