Looking to do this mod on my 620 but looking for some feedback as to if it made good improvements and is worth the time. I have heard that not all saws benefit from this and some more than others. Any info or insight is greatly appreciated.

I recently did some 590 testing. At minimum it needs a muffler mod and I change the nozzle so the carb can be properly adjusted. Here's the vid:
