I got my Xp pro ultimate two weeks ago. Broke in 3 hrs slow and easy. Started doing some hard pulls this weekend and discovered a problem immediately. Under hard acceleration as turbo started spooling up machine lost all power and fell on its face. Let off throttle briefly and reapply same thing. Checked with 2 dealers for help but being Saturday no help from them. Fortunately my mechanic was riding with us and diagnosed the problem. Air intake tube to air box was collapsing under hard acceleration. Took off tube to air box and installed a filter pre screen over opening and fixed problem. Anyone else experiencing this problem? Quite funny telling people all weekend that I had to take parts off Polaris flagship machine to make it run.
