Torque management
So I was reading an older article on TFLTruck and they stated on the newest Super Duty trucks torque management only exists in 1st gear on the dually trucks. SRW they stated it exists in 1-3. Is this information correct? How about the other brands? Similar situation? I know Ram you see nothing but complaining about TQ management, Chevy and Ford not so much.

It's there. You can't have the power we have without completely wrecking the drivetrain wholesale everywhere. Fly by wire throttle, by it's nature, has such things, even if they're limited hardly at all for the most power. Otherwise the throttle is jumpy. We just weaken the tip-in, on sportbikes to make them less jumpy, IE:"better fueling".
White XL's used to have the most torque limiting. Not sure if that's the way it is anymore.
Shift to 4wd and notice how much more bottom grunt the truck has. Being a master tech, I haven't tried to do a burnout with MY F250. I wonder if it's even allowed???

I don’t think it’ll allow something like a powerbrake burnout but I also think the torque is limited in 1st and 2nd. Mine runs like a scalded ape in 3rd and no matter how hard I push, once I hit 3rd gear (around 30-35 mph) it won’t downshift into 2nd...the full-on 900+ ft/lbs will turn the tires in a roll-on on dry streets...it’s no joke.

It’s the traction control too. Yes, you can power brake it, drift it, or do donuts. Just turn traction control off, or use sport mode which is a double button push. It’s the only way your going to get out of a sticky situation, I use sport mode. The torque still has to be limited, or it will tear **** up in the driveline.

The torque curve on these things is amazing, even with the torque management roping the twist in for the first few gears. I use the words "gets up against a gear" and they just pull, and pull, and pull.

A double push of your brights may put you into sorry mode.
A double push of the traction control button (over the stereo) will put traction control in "sport mode". Holding it down for 5 seconds will turn it off.

Ha. The tire dealer probably won't be sorry about it. Your wife and wallet might...

Ah, I hadn't thought to use the hazards to do the two-blink thank you. Here's two blinks and rep for you.

The trucks do pull hard and I have no complaints in terms of driveability.

This is true...2017+ single rear wheel diesels are limited in gears 1-3 while duallys are only limited in 1st gear. Ford specifically cited the reason as being to "reduce wheelspin" which is silly. They put Line-lock on the Mustang with the intent to allow wheelspin but on the diesel they prevent it? Methinks it has more to do with saving drivetrain parts.

Given the light rear end and 900+ lbs/ft of torque spinning the rear tires in 2nd and 3rd on a SRW is going to be an issue that could easily result in a driver loosing control.
Also, a linelock on a pony car is not used when accelerating in 2nd and 3rd gears. Its for doing a burnout in the water box on a drag strip.
