  • 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.
