Bought a new to me 2007 Yukon XLT. Has 59K on the odometer. figured I'd see what she can do in the 1/4 as a baseline for future mods. 15.9 @ 89 was my best run. 1/2 tank of gas and third row seats removed. Not too shabby for something that's at 5700lbs with me in it. No mods at all right now, so the launch and shift from 1st to 2nd was just disappointing. hahahaha.
