sportsman xp 850 programmer

[09xp850le]

anyone out there got a fuel programmer on there 850? and did it make a big difference?

it makes a little difference when stock because the 850 runs a little rich. to get the most results add a air filter and pipe. power comander 5 is the best one IMO.

i would definately get a programmer to richen it out a little.
