I purchased my first rzr a few days ago and it is the turbo. I am curious as to what is the max speed for low and when should I put it in high? My salesman said keep it in high if I plan to run 30+ constantly. He said if I am running 20 or under mainly and sometimes get it up to 30 but back down to 20 or less quickly then it can stay in low. Is this true?

Thank you,
