Preheat the oven to 400 degrees F. Line two baking sheets with parchment paper. Cut the tortillas into 6 wedges each, and lay them in a single layer on the baking sheets.
Mix the melted butter, sugar and cinnamon. Brush the mixture over the tortillas, then flip and repeat.
Bake the tortilla chips for 10-12 minutes, until golden around the edges.
Meanwhile, place the pumpkin puree, cream cheese, powdered sugar, pumpkin pie spice, and salt in a blender jar. Puree until very smooth.
Serve immediately, or chill the Pumpkin Pie Dip until ready to serve.
