I'm also running a 16T on my '13, and according to my fuelly app, I'm averaging 51.4 to date. Before the 16T, while the bike was still primarily stock, I was seeing 55-56mpg regularly. If the odometer error with the 16T accounts for 1-2mpg, I'm still 2-3mpg less than I was seeing before. I'm not terribly geeked up about this though, since I'm still happy to be seeing over 50mpg on every tank. I haven't been using a GPS for mileage, but might run a couple tanks with one to see actual mileage. Other factors I've introduced are a Givi AirFlow, tail box, and occasionally some hard cases (Pelican knock-offs).
All this said, if there's a 10mpg drop, I find it hard believe it's solely because of the 16T.
