Hello from Utah. I am coming over from the General xp4. I bought the new XD primarily for hunting and trail riding. I am a big game hunting guide here in Utah and put the machine to the test this last fall. I put over 1000 Miles on the machine with some desert but mostly mountain terrain. I have been watching this site for a while to gain some info and thanks to all for your input on several items. The rocky terrain here in Utah shredded the stock tires. I just upgraded to some 32" Alpha Valor and looking forward to trying them out. I did experience the low end power problem with the transmission. I had a client and a machine full of gear and powered out on one section of a trail. It was no problem if I hit it with some power but slow crawl it was stuck. I just upgraded the ECU with Gilomen and shout out to them for a 1 day turn around to get it back. I can see an instant change. More power in all scenarios including a lot more low end torque. I am constantly adding things to this machine and love it. The HVAC system is amazing for a Side by side. I used it in 95 degrees mountain riding as well as 5 degree snow hunting days. Enjoy!!!
