Trim fat from pork shoulder and cut into 4 large pieces, roughly the same size.
In a bowl combine the brown sugar, pepper, salt, onion powder, garlic powder and cayenne pepper. Rub the mixture over the pork shoulder and coat evenly.
Add 2 tbsp olive oil to the inner pot and select SAUTE – 30 minutes and press START. Once the pot is hot, add 2 pieces of the pork and sear each side of the pork for 2 minutes each side. Remove pork and set aside on a plate. Repeat with remaining pork pieces.
Once pork is seared and removed from pot, press CANCEL and add 2 cups chicken broth. Use a wooden spoon and deglaze the bottom of the pot, scrapping up all the bits from the bottom of the pot.
Add the remaining ingredients to the pot; BBQ sauce, soy sauce, onion, carrot, celery and garlic.
Place pork pieces in the pot and push them down into the liquid. Secure lid and set to VENT. Select SLOW COOK - HIGH for 8 hours and press START.
When the cooking time is complete, remove pork and shred in a large bowl. Add BBQ sauce as desired or use the juice from the inner pot to dress the meat.
