So this is what it's like to have a 6.2?

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.

And I can tell you that I have 2 rigs right now with 6.2’s. For some reason Big Mama (my 07 Denali) is much funner to drive like that than my 2014 Sierra CC 6.2. Maybe it’s AFM?

Did you disable it yet?

 

[Big Mama]

No, I got it in January but haven’t driven it a lot. How did you disable yours?

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.

I swear I saw the gas guage go down during that rip!

LOL!

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...
