Benefit of a fuel controller in a 2016 @ 6000′???

Do you think I will notice the disadvantages of the default lean fuel of a 2016 at 6000′ elevation and above? If it will run funky I will order buy a controller so that I can install it before I start riding the 2016 Grizzly that I hope to get on Friday. Hopefully the lack of oxygen up here will balance the lean mixture.
