Same bar/chain on both. The STIHL is more of a nascar engine design with a 34mm stroke vs 39mm stroke for the 572xp. I applied the same pull on the handlebar to both as close as I could get , also the STIHL had to cut thru 3knots at the bottom of the cut - the wood was hard maple. I most certainly could make either saw faster by using a thinner base gasket and probably p/u another .5hp .... Squish is .030 on the STIHL and .038 on the Husqvarner - stock base gasket and no machine work. I Could also weld up the combustion chamber and Machine to up the compression for more power but for bucking wood / felling trees these both work well. Either one will do the job but the STIHL is a fuzz quicker and the Husqvarna is a fuzz smoother
