Welcome. Time is irrelevant with Cops and thinner cuts. 1 1/2" chops go longer than 3/4". Cooking to Internal Temp (IT), gives more consistant results.
Chops are Lean and dry out easily. Get yourself a Multi-Probe Thermometer and an Intant Read Thermometer. Pork Chops are best grilled or smoked until the Internal Temp (IT) gets to 140-145°F. These will be tender, juicy and slightly Pink in the center. If Pink pork freaks anyone out, cook until the IT hits 150°F MAX! Still juicy but no pink. Set up your Grill for Indirect Heat, hot on one side, no heat on the other. Place the Chops on th Cold side and cook, turning occasionally, until the IT reaches 120°F. Then finish them over Direct Heat, to Sear, turning every 60 seconds, until the desired IT. You can baste with sauce but be careful not to burn the chops. Move on and off heat as needed.
A soak in a flavorful Brine, 4 hours to overnight, adds moisture and tenderizes. Add a Rub of choice and you are good to go. Below are some recipes I use. Good Luck...JJ
