Yup, SRW has torque management 1st-3rd. DRW is 1st only. ( I usually call it "insane" torque management) even drw will have a less intense torque management in 2-3-4-5-6 gears.
However no matter what even when tuned these will always have some sort of "torque management". Its just reduced to a point where its not as intrusive as the OEM PCM/TCM flash.
Drive a stock SRW, then try out a DRW the way ford sets up the stock DRW PCM/TCM flash is pretty awesome.
When I have a heavy foot I can literally hear the layers of rubber from my michelins being left behind. The torque is absolutely insane on these things. I have had the rear end spin up at 45mph on wet roads when it downshifts before the traction control settles things back. I can easily see how things would get out of hand quickly with this much torque and nothing separating it from the driver!
You forget the dually has a substantially beefier rear axle than the SRW trucks...
Yes, but I doubt that the rear axle is the weak link.
On my SRW truck, turn off the traction control and its pretty easy to break the rear tires loose in 3rd gear on wet pavement. Without trying. Just normal throttle will do it sometimes. Manufacturers are paranoid about such things these days. While torque management surely improves driveline lifespans that's probably more of a bonus to keeping them from being sued for building a truck that is "too powerful".

Its much more responsive.
Having owned a 2017 dually for a year and now on a 2017 SRW for 6 months, I see little difference other than the SRW truck is quicker. Both my dually and SRW have the 3.55 axle ratio. Perhaps you were driving the more common 4.10 axle dually, which will feel more responsive.
