Now, get your temp up high to about 500-600 degrees for a nice sear. Then sear the Tri Tip on each side for 2 minutes, or until the internal temp reaches 130 for medium rare. Be mindful that the skinniest part of the triptip will cook faster than the thicker part of the meat, and also remember that this is a roast so it is best cooked to a medium rare, not well done.

I recommend using a thermapen to check internal temperatures.
