So I have a 2019 Polaris 850 and got it flashed last week by my dealer. This is the 4th flash this ecm has seen and it seems to start easier and run cleaner. I was running hot plugs to make it run good with the last flash but now the stock plugs are working great. From what I understand it also brings the exhaust valves in about 5700 rpm instead of 6000. They also cut the oiling down on deceleration.
Here is a short video link to hear how it sounds. Keep in mind my camera goggles record very tinny sounding.
