well this morning leaving work i fired up the titan and heard tick-tick-tick-tick for maybe a little over a second. sounded like my old silverado when i started it cold. my truck is a 07 with 6000 miles, is this something i should worry about or go get checked out?

Most likely not.
I might not explain this right, but I'll try...

The DOHC engine is chain driven. And those chains are on tensioners, and what you are most likely hearing, is the tenioner adjusting after sitting overnight.
