Can someone verify if this is the real 6.2 experience?
So this is what it's like to have a 6.2?

Yes, but that truck has been modified some. I tell you, every time I drive the 6.2 Sierra it puts a smile on my face!

The 6.2 is a beast compared to 5.3!
if it's @randeez incarnation then yes
the Silverado's are light in the @ss so the burn out is not too much of a stretch

I have the 6.2L (420hp) in my 2021 Yukon Denali which is a significantly larger vehicle than my previous 2004 SRX V8 (325hp) - and it's pleasantly responsive. Maybe not quite as sporty (tight cornering) as the SRX but feels like it's in the ballpark acceleration wise - e.g. fun to drive for sure!
And towing 5,000lb is night/day - SRX strained but Yukon just plows ahead as if it's nothing.

That's music to my ears. Sounds like my Tahoe when it was running good--except my exhaust was a little louder.
I wouldn't do that with a G80! But yes, the acceleration is really good, even stock, but I suspect that truck has been modified, as James says. 0-60 is about 6.4. My father-in-law drives a Porsche and he thinks the 6.2L in the Denali's we have is awesome. Grins ear-to-ear every time I punch it and leave everyone else in the dust. Especially the 2012 with the bigger cam. I can't vouch for the wheelspin because the Denali SUV's drive all 4 at the same time. Need to get feedback from someone with a 2WD Denali or Escalade.

I wouldn't know. I can't do burnouts. I have AWD.
And i haven't tuned it because, frankly, I don't trust myself. It's dangerously quick for a 5500-lb truck.

Any upgrades to a 6.2 definitely mean upgrades to the brakes and suspension are in order. It’s at the absolute limits of its class.
I wonder what GM did to the Esky V to prep it for 682hp compared to a standard truck?

Here is my 09 Tahoe L9H 6.2. This video is taken at 5,000 ft above sea level in Colorado.

My 2013 Escalade ESV pulls like a freight train. I love the 6.2L!
It has spoiled me.
Definitely correct about brakes. I am looking at the 'big brake upgrade' next.

Did you disable it yet?

Thankfully mine is an 03, so no AFM for me. Lots of guys use the device that plugs into the OBD port, which disables it. Other guys will just have it tuned out and leave the AFM components in the motor, while some guys take all the AFM components out AND have it turned off with a tune. Take your pick.

Haha, you're probably right, especially since I only use E85
I'll have a new video coming soon, I had a new trans/torque converter installed. It feels quicker now.
2017 Denali here. What’s not to like about 420 HP, 460# torque and 21 mpg on road trips? I tow a lot with mine (almost 100 miles towing the boat yesterday) and the extra power is really appreciated on on-ramps.
I wouldn’t say no to beefier brakes though.

My 18 Denali has a 6.2, but I like my CTS-V 6.2 a little bit better...
