Basically, I’m sitting at a stop and I just let clutch out slowly not even touching the gas until the clutch is fully engaged. You can do this in reverse as well. And on hills! I’ve never experienced this on any other car in my life. Maybe a tractor.

I think all of the cars I've owned that had EFI could be driven away from a full stop without using any throttle. The amount of slope tolerance did vary as some function of torque at idle and overall gearing, though. It's relatively easy to build a "stall-saver" routine into the programming, and this is something for which the resulting output is subject to calibration. Nominally it's there to prevent the engine from stalling when a heavy accessory load is suddenly applied, but a drive load ends up provoking the same response.

Anyways, if this is an option this might be the reason that the car boggs on takeoff. The torque mgt might be getting too much input from the throttle position at one time. It might be the explanation about why first gear feels so tall. It could also explain the difference in taking off each time and the car does not respond the same to your foot position. If that makes sense?”
Thoughts?

If the eLSD is normally 'open', I suppose you could be getting a little one-wheel peel before it can be locked up (which you might feel happening). Just not enough to generate any tire noise. Perhaps the rear ABS wheel sensors
are involved here, and there may be some tolerances involved that conspire against some cars more than others.
Does this happen on launches and street starts from a full stop made in 2nd gear?
