Had a 2011 xtx with 180 hurricane kit, friend had well setup 800 polaris, pretty much even to 500' then apex would slowly pull away. Now have 19 sidewinder, when stock he had me for 300' then would pull him in on 850 doo, now I have hurricane sm tunes and he has 850 poo, he had 1 sled for maybe 50' then in his words I hit another gear and was gone lol
