Cut pork shoulder in half so you have two 1 pound pieces.
Mix all of the dry ingredients together and rub them on to the pork.
Place pork into the pressure cooker and add BBQ sauce and water.
Lock the lid in place and turn the valve to SEALING. Set to HIGH pressure for 40 minutes
When the timer goes off let the pressure cooker do a natural release for 10 minutes. Then turn valve to VENTING and release any remaining pressure before removing the lid.
Remove the meat from the pressure cooker, leaving behind the liquid, and shred the pork. Add more BBQ sauce to the meat if desired.
Serve immediately or store in an airtight container in the refrigerator until ready to use.
