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

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?

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.

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.
