Apply Neely's Seasoning to each pork chop. Place pork chops in a large freezer safe plastic bag. Pour 2 cups of Neely's BBQ sauce into bag. Marinate in refrigerator for 8 hours.
Place pork chops on grill and cook until internal temperature is 160 degrees F. Reapply BBQ sauce to pork chops prior to serving.
Mix all ingredients together in a small bowl.
Combine all of the sauce ingredients in a large saucepan or Dutch oven.
Over high heat, bring ingredients to a boil, stirring frequently to prevent sticking.
Once sauce comes to a boil, reduce temperature to low and simmer, uncovered, for at least 2 hours.
