Tuning wrx for economy rather than performance

Has there been any discussions of this?

Why should there be? This is a car you buy for performance, not
economy. Of course, performance improvements will usually make the car
more efficient.....and therefore more economomical if the extra
performance is not used. What's the point of performance enhancements
if you don't use them, though?

If you drive gently the turbo won't do much, which will increase your MPG.
Shift early, anticipate stop lights, and don't get into drag races with
Hondas. Air resistance starts to get important around 50 MPH, so stay in the
30-40 MPH range. Pump your tires up a bit harder. Use synthetic 5W-30 oil
instead of regular 10w-30. Use synthetic oil in the transmission and axles.
Keep the windows rolled up. Don't run the A/C. Put on skinnier tires...

Or, trade it in on a hybrid.
 
You could run a vacuum hose from the turbo compressor outlet to the
wastegate actuator. This would prevent the wastegate solenoid (aka
"bleed solenoid") from increasing boost above wastegate spring
pressure. The result would be a reduction in max boost from about
13.5 psi to around 7-8 psi. It's completely safe for your engine, and
you will see better fuel economy, assuming that you sometimes got into
the boost before this change. Lots of people have run their WRX like
this, some for extended periods of time, but it's usually the result
of a vacuum plumbing error, not a desire for economy.
