How do you change mapping 2012 YZ450f

I could not find any stickies on this either. I thought the owner could simply use some type of plug-in to easily change the power characteristics on the 2012 YZ450F. I thought the bike came with an alternate program in the form of a little plug. Mine came with a little plug. It looks like an electronic part. If so, where do you install it or am I mistaken? Bronco.

the easiest way and fun to play with is the gytr power tuner, 250 bucks, i believe its avaiable at the tt store w/ free shipping
