Tyler Florence has a surprise for the four remaining food truck teams: a taste of the Nashville's famous hot chicken, prepared by Nashville native and owner of restaurant 400 Degrees, Aqui Hines. The teams sample and see if they can take the heat, then Tyler challenges them to make their own versions of hot dishes -- but without chicken. Aqui tastes the dishes, awarding the winner $500 in their till. On the second day in Nashville, Tyler has the teams to create their own self-promotion, much like the many artists in the city. Country singer Craig Wayne Boyd judges their promotions, rewarding the winning team with immunity.
