In a large bowl, stir together the cheese powder, tomato powder, buttermilk powder, onion flakes, garlic powder, paprika, sugar, salt, and MSG.
Lightly brush or spray both sides of each tortilla with oil. Cut each into 6 or 8 wedges.
Preheat the air fryer to 350°F for 2 to 3 minutes.
Arrange the wedges in a single layer in the basket. Air fry for 5 to 7 minutes, flipping halfway, until golden and crisp. Work in batches.
Transfer the hot chips to the seasoning bowl, mist lightly with oil, and toss to coat.
Spread on a tray to cool for a few minutes before serving.
