[Armada]

The diesel is in a 3/4 ton truck. About 6500 lbs. It will be quick, but that weight is a killer. He'll not overcome spotting you over a thousand pounds in weight if he is stock.

The 6.0 354 bhp 1500 Silverado will be just about a dead even match for the Titan. It's still mated to a four speed auto, and still does not have the low gearing we get from having the equivalent of 4.10 gearing in our lower three gears. Those are two strikes against the high output engine. He'll probably be wearing 20 inch rims too, which will hurt him some.

I've run Denalis and Escalades with that 6.0 engine. My Armada runs pretty consistent 14.8's to 15.1's depending on temperature and humidity. No mods of any kind except the "airbox mod" and a K&N drop-in and synthetic fluids in the engine and both diffs.

Against the 3 or 4 6.0 GM SUV's I've run, here is what I see: Our gearing helps a great deal off the line. I pull away coming off the line. In the midrange, the GM tries to close the gap some and then I pull away on the top end.

Typically by 90-95 mph I am holding a 2-3 length lead. That's about 2 tenths of a second difference or thereabouts.

I would expect a Titan/6.0 1500 Silverado to be similar.
