If you want a finished product with and internal temp of 163 you most likely want to take it off the grill when it remote read thermometer reads between 153-158 deg.

FYI the doneness criteria for pork changed about a year ago.

"New cooking guidelines from the nation's food-safety agency confirm Pork Checkoff research that shows pork can be consumed safely when cooked to an internal temperature of 145 degrees Fahrenheit, followed by a three-minute rest time. The guidelines were announced today by the U.S. Department of Agriculture's Food Safety Inspection Service (FSIS).

The new recommended temperature is a significant 15 degrees less than what was previously recommended and typically will yield a finished product that is pinker in color than most home cooks are accustomed to.

"Our consumer research has consistently shown that Americans have a tendency to overcook common cuts of pork, resulting in a less-than-optimal eating experience," said Dianne Bettin, a pork producer from Truman, Minn., and chair of the Checkoff's Domestic Marketing Committee. "The new guidelines will help consumers enjoy pork at its most flavorful, juicy - and safe - temperature."

The revised recommendation applies to pork whole-muscle cuts, such as loin, chops and roasts. Ground pork, like all ground meat, should be cooked to 160 degrees Fahrenheit. Regardless of cut or cooking method, both the USDA and National Pork Board recommend using a digital cooking thermometer to ensure an accurate final temperature."
