I have a 2018 polaris ranger 1000xp, I'm sure it's clutch issues but not sure where to start, it letterally feels like my machine is shifting gears, ill get up to 40mph it will shift and rpms will go down then I accelerate to 50 it shifts again, rpms go down and same thing again when I hit 60, I noticed it sometime after I installed the gilomen tune, but I feel like it wasn't doing that right away after the install. I'd really appreciate any advice I can't seem to find anybody else with these problems
