Obviously this is a very open ended question, as different saws will react differently, and different tuners have different approaches. But what are the downsides to a ported saw?
Coming from a background of two stroke bikes, I have rarely seen a port job that really improved a bike, they would become complete top end screamers, and bog down trying to come out of corners, or they would become hand grenades.
A saw operates over a smaller rev range, so perhaps raising the power, but reducing the operating range works? I've noticed some tuners talk about widening the operating range, perhaps this is advantageous?
Obviously there are advantages with raising compression, cleaning out casting imperfections and smoothing shapes, lowering cylinders requires port timing to match. I get all that. But nothing comes without a price. Increased noise - almost all the tuners seem to open up mufflers. Increased fuel usage, well more power requires more fuel. Increased emissions, as epa type organisations have clamped down down on maybe this is where the tuners come into their own?
I've only ever run stock saws, and some are better than others, some just go about the job in a different way. Some will just keep chugging away, others scream but if they bog at all its all over.

Sure you may get more wood on the ground, but lets be honest, who has the hard numbers on that? I honestly haven't seen anything 100% conclusive. IMHO the best thing you can do to a work saw is mod the muffler.
