6. Turn barbecue on high. Let barbecue preheat with lid closed until 450F or more.
7. Turn 1 burner off and place tri-tip on barbecue over the off burner, out of direct flames.
 This will give you nice sear marks without burning. Close the lid and do not disturb for 
20 min. Note: with 1 burner off, you should maintain about 350F.
8. After 20 min on the first side, turn your off burner back on to high. Now, turn off 
a different burner, and turn your tri-tip over and place over the newly 
turned off burner (again allowing a sear without burning) for about 20 min with lid closed.
9. Turn all burners to low-medium, and cook tri-tip for another 15-20 minutes, 
depending on size of your tri-tip and desired doneness. Check steak every 5 minutes, 
turning as needed to maintain a crispy outside without burning.
10. Tri-tip is done when internal temp of the thickest section reaches 140F 
degrees (Medium-Rare) or 155F degrees (Medium). Remove from grill and 
cover with foil to rest for 5 minutes.
