I knew that Nissan Ester Oil lubrication capacity would have dampened the torque somewhat but I am surprised that the dampering was substatial enough to actually notice the difference when I switched to full synth.

Switching to full synth must have given me back at least 5 to 7 ft-lbs of low-end TQ to be able to notice it that much and chirp to 2nd!.
