I just went out and tried the same, I think it is improved, should have measured it to be 100% sure. I am 6' tall and now when open tailgate barely touches my head from the sides of the latch area, however, the latch itself still hits my head. Also, I could still raise it by hand another 1.5"-2".
I tried to reboot the module using ForScan while the tailgate was fully open, but this made it think it closed, pressing any button to close the tailgate just caused the latch to make a sound like it's trying to unlock without any movement. Had to close it by hand for it to then function normally.
