Cut the pork into quarters and rub each piece well with salt, pepper and 1/2 of the packet of Sazon Goya.
Set the instant pot to the sear or brown function and heat the diced bacon until sizzling, about 3-5 minutes.
Brown each side of the roast pieces, about 5 minutes and then turn off the instant pot.
Remove the excess grease from the pot but leave in the bacon and any browned pieces on the bottom of the pan.
In a blender, combine the chicken broth, chipotles, crushed pineapple and the rest of the packet of Sazon Goya and blend until smooth.
Pour the liquid over the roast and bacon and stir well to get any pieces of roast off of the bottom of the pot.
Seal the pressure cooker and cook for 35 minutes.
When the cooking time finishes, allow the instant pot to slow release for 10 minutes and then release the rest of the pressure manually.
Check that the pork has reached an internal temperature of at least 145 degrees Fahrenheit and that the pork shreds easily. If not, reseal the instant pot and cook for another 5-10 minutes before checking again.
Once the pork is well cooked, shred the pork and then return it to the sauce with the bacon.
Serve hot in corn tortillas, optional, and topped with chopped cilantro, white onion and lime wedges, optional.
