2013 Scrambler 850 Throttle Issue

Hey Guys. New to the board. So be easy on me.
So I recently acquired a 2013 Scrambler 850 and am having one issue with it.
The engine starts up and runs perfectly. If I ease on the throttle, everything works perfectly. If I hammer down on the throttle, it immediately boggs for a second, then revs up and takes off. The person that had it before me installed a snorkel kit on it. I thought it may be an air issue but I ran it with the cover off of the air box and it did the same thing. Air filter is clean. Again, it runs great if you just ease into in then get on it but boggs down if you just "floor" it. Something isn’t right. Any help would be greatly appreciated.
