It depends on the designs. Most newer saws gain less than older models. The manufacturers figured out a lot of stuff over the years.
When a saw gets ported, we are just trading certain traits away for others. We sacrifice noise, fuel economy, emissions, and/or reliability for more power. If anyone thinks they can beat the Billion dollar OEM manufacturers at their own game from their basement they are certainly fools.
I’ve only done one 620 and the guy is pretty happy with it. I found it needed better air filtration and a gutted muffler with a larger factory opening to not be held back. Ran pretty well and had a good low end for a saw of it’s size.
