New Personal Best - 2015 Sierra 6.2
2015 Sierra 1500 cc/sb 4x4 Denali - 6.2/8 speed - 3.23 rear gear
Very happy with this truck. It's quiet, smooth, powerful & gets amazing fuel economy!
It's completely stock and weighs 5700lbs. My race weight was 6000lbs. Temps today were mid-40's / 50% humidity.
My best pass was 13.77@99mph. Best 60 foot was 1.91.
Leave at 1200rpm in "4wd Auto" --- "TC" Off, then switch back to 2wd after launch.

Nice, what rear gears are in it?.
I just picked up a new 2015 Sonoma Red Metallic GMC Sierra All Terrain with the 6.2/ 8 speed auto this Friday. It feels good at part throttle compared to my old 08 Denali.

3.23 gear. I think that is the only option on the Denali.
I really wanted the 3.42 trailer tow package but they had this in stock and I did want the Magnaride...
Love the truck aside from the gaudy frontend

Why are you putting it in auto and not 4x4 to start? I used 4x4 throughout the whole pass because I believe I read somewhere that the trucks do not disengage the 4x4 when you are wot. So switching it back to 2wd during the pass doesn't change anything until you let out.

Very impressive for a stock truck.
Mine is the same except double cab.
