Misfire under acceleration

Start from the beginning 2011 screw 4X4 ecoboost 46,000 miles, under wide open throttle and over 3,500 rpm I'm getting a misfire, looking for ideas or diagnosis "I usually chicken out when I hit 80+ in 3rd". Misfire occurs in 1st, 2nd, and 3rd don't have enough road to try a higher speed or gear.

First idea that comes to mind is taking it to your local Ford dealer. It's still under warranty.

Plugs maybe. Any codes? I've seen whispers on the interwebs about spark plug issues on Ecoboost trucks in regards to carbon tracking, and wild gapping.
