In a large bowl, whisk together 2 Tablespoons olive oil, 1 Tablespoon sriracha, 1 Tablespoon honey, 1 teaspoon garlic powder, 1/2 teaspoon onion powder, and 1/2 teaspoon salt.
Add 1 1/2 pounds boneless, skinless chicken breasts cut into strips and toss to coat evenly. Cover and marinate for 15 to 30 minutes, or refrigerate overnight.
In a separate bowl, stir together 1/3 cup mayonnaise, 2 Tablespoons sweet chili sauce, 1 Tablespoon sriracha, 1 Tablespoon lime juice, 1 teaspoon honey, and a pinch of salt. Refrigerate until ready to serve.
Thread the marinated chicken onto soaked bamboo or metal skewers, leaving space between each piece.
Preheat your broiler on high and place the oven rack about 6 inches from the top. Line a baking sheet with foil and place a wire rack on top. Arrange the skewers on the wire rack.
Pour half of the bang bang sauce into a separate container for basting (reserve the other half for serving). Brush the chicken with some of the sauce.
Broil for 5 to 6 minutes, flip, brush with more sauce, and broil for another 5 to 6 minutes, until the chicken is cooked through and slightly charred on the edges (internal temp 165°F/74°C).
Serve with remaining sauce on the side and garnish with Chopped cilantro or green onion, Toasted sesame seeds, and Lime wedges.
