<p>Hello mate. Just looking into porting now....I have a 576xp autotune and a 560xp autotune....can these be ported? what are the benefits exactly ? I am full time forestry cutter....I have just ordered the large heavy duty air filter and top housing case to accommodate it.</p>

<p>I dont want to ruin the lifespan on my saws but would like the extra grunt etc etc...please advise.</p>

<p>Im in Devon by the way...cheers</p>
