Take the pork tenderloins out of the packet and pat them dry with a paper towel, then trim off the silverskin (I personally leave the fat).
Fold the tails up and tie them with twine at the top, middle, and bottom.
Place them on a wire rack and cover with bbq rub.
Fill up the hopper with pellets and set the grill at 275°F. Let it preheat for about 15 minutes.
Grab the wire rack with BBQ gloves and place it in the center, the heads facing toward the fire.
Place thermometer probes in the middle of the first and last tenderloins.
Every time they heat up by 15°F, rotate them 90 degrees until you reach the beginning again.
Close the lid and let the tenderloins cook until they reach an internal temperature of 130°F (about 1 hour).
Squirt the glaze along the center of each tenderloin. Use the basting brush to dab it on and spread it as much as possible.
Close the lid and let them reach 135°F before adding another coat of glaze.
When they reach an internal temperature of 140°F, remove the wire rack and place it on a cutting board.
Loosely tent with aluminum foil and let rest for about 15 minutes.
Slice nice and thin against the grain to serve. Optionally, add more glaze before serving.
