They're the same machine so the numbers should help. There is no tuning system for 3D. Wing told me the 3D tuning they did is for when you have the glasses on and the effect the glasses have on the levels and grayscale tunings. It's set for max contrast and D65k grayscale while viewing with the glasses.
If one was to tune it without the glasses it would lose all that high brightness and the grayscale would be off (when putting the glasses back on).
I got 1700lumens out of the 3D setup and 1200 lumens out of 2D.
Had to raise the numbers because when I used my light meter I forgot to have the projector at max zoom. Max zoom adds about 20% to the lumens numbers.
