Gas MPG vs. turbo size?

I thought It'd be useful, and I haven't seen it yet.

I've got an 02 wagon and Im considering a bigger turbo, maybe vf34. But I got thinking, since its a daily driver, how it will affect the gas MPG. Then I got to thinking it might be useful information for people to know what MPG they could expect to see on all turbo upgrades.

I thought maybe people could post their setups in this fashion, and if I get enough responses, I'll put together a chart:


What year Subaru:
What model subaru:
What turbo:
Supporting mods:
MPG (average):
Type of Driving (Street, Highway, or Mixed):
Pro-tune or off the shelf map:
