Season baby back pork ribs with salt and pepper on both sides. Cut rack in half. Place ribs in a teepee formation onto the rack. Pour a little barbeque sauce onto each half and let run down the sides. Close and lock the lid.

Select Meat setting according to manufacturer's instructions; set timer for 30 minutes. Allow 10 to 15 minutes for pressure to build.
