If your computer has a BD PROCHOT throttling issue and using ThrottleStop to disable the BD PROCHOT signal path fixes this problem, it only makes sense to always leave BD PROCHOT disabled.
This type of throttling is over used by manufacturers and is rarely if ever necessary. Only leave BD PROCHOT enabled if you like using a computer that randomly slows down to a crawl.
Keep in mind that if your CPU ever gets too hot, it will still thermal throttle and slow down to protect itself whether BD PROCHOT is enabled or not. BD PROHOT and PROCHOT (processor hot) are two different things.
