This is about the same results I had on my dsm.

You still have to consider that if you could remove the transfer case drive-line and all the AWD rear parts and and replace them with a lighter FWD rear end parts you would increase your FE by a lot. All these parts have more mass and parasitic drag, so by reducing their mass and parasitic drag you would increase you FE.

This is the same as when testing a car in awd on a chassis dyno verse fwd mode on a chassis dyno.
