Haven't driven it yet. Power savings should be 40w. However, another update:

Friday, when my wife went to work it was warm - in the 70's - and she set an almost record low in gas mileage at 48mpg, so I pulled the throttle smoothing circuit out. I put the +12v tender on, in the evening a coldfront came through, and on Saturday when she went in to the office it was about 35F and she managed 63mpg. She reported no unusual circumstances on either trip.

So, throttle smoothing circuit + warm weather = 48mpg
Fully topped 12v + cold weather = 63mpg

EDIT: I did notice what johnlvs2run mentioned about the throttle smoothing circuit. For whatever reason, it seemed like I was needing to be in a lower gear to climb the same grades, though I'm at a loss for an explanation as to why. For now, I'm not recommending it.
