Spray your Instant Pot or Pressure cooker with cooking spray and place the pork tenderloin in, pouring the diet Pepsi over top.
Stir together the BBQ sauce (but save 1/2 cup for later), brown sugar blend, apple cider vinegar and garlic salt and pour over the pork.
Place the lid on your Instant Pot sliding into locked position. Set it to cook for 45 minutes. Do a natural steam release for 10 minutes, then turn valve to vent position.
Once the float valve has dropped, remove the lid and use 2 forks to shred the pork into small chunks. Drain the liquid from the pot and mix the remaining BBQ sauce in with the shredded pork.
Serve on hamburger buns and enjoy!
Follow the above instructions for preparing the pork, but instead cook on low for 6 hours in your slow cooker before shredding the pork.
