I had a 2010 with a 6.2 and 3.42 gears and it would NOT spin the tires from a dead stop. After a tune it would do it easily and catch 2nd most of the time. I now have a 2011 with the 6.2 and 3.73 gears and it would spin the tires stock. After a tune, and CAI it will get pretty stupid when ever you want it to. I actually had my tuner put some more TM in the truck because all it wanted to do was spin the tires when you mashed on it.

Awesome, who did your tune?
Dyno tune or mail order?

Yup mine is a 3.73 truck too might have something to do with it

So apparently I have no signature when I post in the mobile version of the site. Truck in sig, no performance mods.

I have a hard time believing going from 3.42 to 3.73 can make so much difference considering 1st gear is already so low in the 6L80E. My boss has an '08 Escalade AWD w/ 22s and it can scratch all 4 tires on launch. Do I go to the dealer and complain that my truck won't smoke em up?

That should be good for a laugh! Do us a favor and shoot some video.

I think Escalades have 3.42 gears too. That's interesting. Is he stock tuned?
