Pre-heat barbecue to hot. Grill pork over high heat, basting with the other half of the marinade. Turn and baste pork tenderloins frequently. Continue grilling until the pork is nicely browned and internal temperature reaches 155-160°F (68-71°C) with a meat thermometer (about 20 minutes). Do not overcook, a little bit of pink is alright. Remove pork from grill, cover with tented foil, and allow resting for about 10 minutes.
