I was look for someone that has run auto tune on a 2010 800 rmk at around 1200ft to see what they got for a map? I tried dynotech Jims and it didnt work on my 800 (had a worse midrange stumble) but put it on my friends 09 800 with the update and he loves it said she never has ran this good so there must be a difference between the updated 08's and 09's to the 2010's
