I think you'll find that average mpg varies greatly even for stock cars (search for threads). I think a better question is, how many percent did your mpg drop after adding FI under the same driving conditions...

In my case about 10% drop in fuel economy.

Same here, with the ESS VT1, I lost about 10% MPG, I am switching to the TX2 with a little bigger injectors so it might be down ~ 12% (just a guess).
