Hey, i have a 2010 polaris. it has 3900 miles on it. sled ran mint up until i went up north with it last week. at 1/4 throttle it runs fine. starts fine and idles fine, goes into reverse fine. at mid range it stumbles and falls on its face. and wide open it rips for about 4 seconds then it falls on its face. it does have the latest software in it. it had ran awesome up until 3900 miles. just curious if someone else has had this problem. i did put a mbn can on it and it ran fine. then it got really loud the other day like it blew apart. could that be causing it to stumble.
