In short, IOPlatformPlugin is power management, CPU scaling, idle frequency (and others). How much the following helps is arguable.


Disable SIP in recovery (CMD+R on boot), open terminal (CMD+3 i
think), 
csrutil disable 
Reboot into MacOS, move
/System/Library/Extensions/IOPlatformPlugin.kext to / or somewhere
else 
sudo mv /System/Library/Extensions/IOPlatformPlugin.kext /
(terminal) 
Rebuild cache sudo kextcache -i /, reboot
Re-enable SIP in recovery csrutil enable
