Just tossing ideas here. Are the torsion bars on the correct sides? They are side specific as in there is a left and a right bar.
I couldn't read the original paragraph all the way through.
Is the center link on right-side up, or correct left-to-right? They can be put on the wrong way.

Front wheels toe in under power... a lot!
I just put a leveling kit on my ‘04 4wd Suburban 1500 (torsion keys in the front, spring spacers in the back, new extended shocks all around, and wheel spacers all around for my eventual new wheels and 33s). When I’m on the throttle, my front wheels toe in a lot under power. I can stick my head...

And, then after being to 2 different shops a total of 6 times, you subsequently manually re-adjusted the alignment using tape?

What brand of parts were in the 13 piece set from 1a auto? Chinese cheap stuff or actual good known product?

I have to think there is a pitch angle issue, for it to pull the suspension down in one direction, and push it up in the other. I am thinking the that either cross caster is off.. I am going to have to ask my shop to see what they think.

That has got to be some of the craziest videos i have seen good job.The only thing that could make that suspension bind and go up several inches is the torsion bars flexing.I would start their and see whats up with that.In the one video you can see the one end of torsion bar go up several inches and with the bolt you screw up or down to control the load it shouldnt be moving at all.I would point your camera at that adjustment bolt on the torsion bar and lets see what that is doing.Great effort on making the videos.Im betting 80% of mechanics would be puzzled.To lift an entire suspension shock control arms everything it has to be a strong part twisting or flexing-my first guess torsion bars

So in this video..
I see the tie rods moving in/out, but I dont see movement out of the pitman arm.
The problem with that is, this wont solve the problem, its just another piece to the puzzle.

And in this video..
I can clearly see the lower control arm bolts moving. They shouldnt.

If you can, get one more video of those 2 bolts to the right of the Torsion Spring, kinda close. Make sure to hit a few small bumps like you did in the video above.
Judging by the dirt/grime I am seeing on the lower control arms. I am guessing that bushings/lower arms were not part of the kit. And my eye is telling me that there is the problem..
BUT.. it should be doing the opposite of whats its doing if thats the case. Me and 2 of my mechanics agree on this.
So I am at a loss..

One of my mechanics just told me to have you lift the front of the truck, and support it from the FRAME behind the wheel. This will allow the suspension to be in full sag/droop. Then to take a pry bar, and put it in behind the bracket for the rear control arm bushings. You should have little to no movement. He is betting you have a lot of movement.
This may be difficult to move/pry on because you are still going to have tension from the Torsion Spring, and the control arm resting on the jounce pad (I think).
He is also one of the mechanics that says that your symptoms dont correlate with the problem.
So as I said above, this may just be another piece to the puzzle.

This is the video that shows the rear of the torsion bar moving up and back down 2-3 inches at least.This has the adjusting bolt on it and under a massive amount of force-the end of that should not move at all just going in reverse.Seems like the bolt is coming off the keys-im still going with torsion bars in wrong or something of that nature.You can also see when the rear of the torsion bar starts moving its picking up the control arm and raising the vehicle.Look at your adjuster bolts and keys again-make sure torsion bars are on correct.

How about posting a printout form the alignment shop?

Same goes for the stabilizer bar. If any of those parts are flipped around or the hardware isn’t to torque specs - in some cases over torqued can cause issues as well, that can lead to the toe in / toe out problems you have.I couldn't read the original paragraph all the way through.

Just a random thought, does your vehicle have autoride? If so has your suspension yaw rate sensor been checked?
