Someone said they've maxed out the power before the truck does a "wheelie" or, more technically, when there's so little traction/weight on the front axle that the truck is uncontrollable. They've countered it as much as they can by making the truck squat in WTF mode.

If you put the truck into "my mode" and turn acceleration up to adrenaline, it's about as close as you can get to WTF mode without being in it. The truck still really shows it's weight and softness of the suspension though."In the early days when we were just trying to balance the front and rear torque, I got the front end to lift," he told me. As it turns out, so much of the car was developed digitally that, when it came time to do real-world testing, there were a few unexpected quirks. "We had to back off the torque on the front end," he added, just as he prepared the Hummer for another launch.
The GMC Hummer EV Could Pop Wheelies Before Engineers Intervened
Chief engineer Al Oppenheiser told us the wheelies didn't make the final production cut because of "functional safety reasons."
I'm still waiting for my "spring" delivery to be built, but understand WTF is significantly faster/more powerful than normal mode. Seems like there's at least daylight to make normal mode closer to WTF in terms of power/acceleration before popping down to what Tesla refers to as cheetah stance. Also, presumably later models without the MT tires will presumably have less issues with chirping tires off the line.
WTF mode hits so hard because the rear suspension is already basically on the bump stops. You can just drive around in it but it's pretty uncomfortable if your roads aren't smooth.
With all the power this truck has, tire friction becomes the limiting factor for acceleration. The acceleration of the Hummer is already near 1g in WTF mode. You need special racing tires to handle more.

Even driving in this mode is not the full power when you launch it.
It might be a while before a reputable tuner (some fly by night place may do whatever and not care) shop gets into tuning EVs that much. The stakes when things go wrong are a little higher. For instance, if you push an ICE too far something fails and the engine dies, your gas tank doesn't explode/catch fire as well. Top speed is just a tire thing. You're close to 5 tons on 4 R-rated off road tires, they're just trying to keep them from exploding. I personally wouldn't go faster without some higher rated tires that can handle that load.
The Hummer launches as hard as you can, but starts pulling power back at about 20 MPH, by 60 mph it has pulled back 200 HP or so, this is likely for battery preservation.
How do you know this? I would like to know more.
