Remove the Pie Crust from the fridge. Allow to sit at room temperature for 10 minutes.
Place the pie crust in the preheated oven and bake for 10 minutes. Remove from the oven, and set aside.
Adjust the oven temperature to 325°F.
Prepare the caramel syrup by placing butter, brown sugar, granulated sugar, and maple syrup in a deep, heavy-bottomed saucepan. Cook over medium-high heat, until the sugar is completely dissolved and the mixture is glossy.
Remove from the heat and set aside to cool. Once the syrup is at room temperature, beat in the eggs one at a time until smooth.
Sprinkle the chopped toasted pecans into the prepared pie crust. Pour the syrup over the pecans, and arrange the decorative pecans on top.
Bake for 40 to 50 minutes, or until the edges of the filling are set but the center is still slightly wobbly. If the crust browns too much, cover the crust with strips of foil and continue baking.
Cool the pie completely before cutting and serving.
