Cook the rotini in salted boiling water; save 0.5 cup pasta water and drain.
Season the chicken with 1 tsp chili powder, salt, and pepper and cook in a little oil in a large skillet over medium-high heat for 5 to 6 minutes per side until 165°F; slice.
In the same skillet, cook the corn without stirring for 3 minutes to char it, then stir and cook 2 more.
Lower the heat and stir in the mayonnaise, sour cream, juice of 1 lime, the remaining chili powder, and most of the cotija, then toss in the pasta with a splash of pasta water.
Top with the chicken, remaining cotija, cilantro, and lime wedges.
