  • I thought I'd post up the graph for my 592xp its a 2022 serial number saw, I've seen other dyno tests of the 592 and all of them put out 8.4-8.6hp stock, you can see mine got to only right about 8hp.. but now being ported by Joe at HMWF it pulled 9.29hp and 6.11tq (an increase of 16.416% for HP and 14.42% for TQ)170760016427718687746914512409.jpg
    HMWF LLC 572xp dyno figures torque increase of 17.92% and horsepower increase of 17.08% still haven't gotten the chance to go cut
    Thanks Joe!

    I just got my 550xp mk2 back today from @Red97 at HMWF LLC. Great packing job and awesome dyno figures for HP-TQ increases of 14.82% horsepower and 20.3% on torque vs stock.. if you can see the graph the power peak was not only increased but much broadened over a wider area.. very happy! Now I gotta go find something to cut. Thanks Joe! Can't wait to see what you do with my 572.
