Prepare the grill for direct cooking over high heat ( 525° to 575°F).
Brush the cooking grates clean. Grill the tomatoes and jalapeño (skin side down) over direct high heat, with the lid closed, until the skins are blackened and blistered in spots, turning as needed. The tomatoes will take 4 to 6 minutes and the jalapeño will take 2 to 3 minutes. Put the tomatoes and jalapeño in a food processor along with the remaining sauce ingredients, and process until smooth. Season with salt and pepper. Transfer the sauce to a medium saucepan and bring to a boil on the stove. Reduce to a simmer and allow to cook until the sauce has thickened slightly, 5 to 10 minutes, stirring occasionally.

In a small bowl mix the rub ingredients.
Lightly brush the tenderloins on all sides with oil and season evenly with the rub, pressing the spices into the meat. Allow the tenderloins to stand at room temperature for 15 to 30 minutes before grilling. Reduce the temperature of the grill to medium heat (350° to 450°F).
Lightly brush the tenderloins on all sides with oil and season evenly with the rub, pressing the spices into the meat. Allow the tenderloins to stand at room temperature for 15 to 30 minutes before grilling. Reduce the temperature of the grill to medium heat (400°F).
Grill the tenderloins over direct medium heat, with the lid closed, until the pork is barely pink in the center, 15 to 20 minutes, turning every 5 minutes. Remove from the grill and let rest for 3 to 5 minutes before slicing. Serve warm with the sauce.
Grill the tenderloins over direct medium heat,with the lid closed, until an instant-read thermometer inserted into the thickest part of the pork tenderloins registers 145°F (or your preferred doneness), 15 to 20 minutes, turning every 5 minutes. Remove from the grill and let rest for 3 to 5 minutes before slicing. Serve warm with the sauce.
