Default MPG update - take it to the dealer?

I brought up my poor mpg with the dealer today - so far working hard to get 22 mpg in 60/40 city/hwy. I'm trying really hard to drive with economy in mind and finding it really hard to get close to the combined mpg. I don't expect to get exactly the combined mpg but I really think that 22 for city/hwy mix that includes nice 12 mile 60 mph stretches with no traffic ought to get me higher than 22!

I was told that some other Impreza owners had mentioned this too. I was advised that since it seemed like I'm doing my part (not trying to drive like a maniac and watching the Eco gauge) it might be a good idea to bring the car in for what he described as an "ECM Flash". He said he's seen this issue in the past with Outbacks where for whatever reason the car leaves the factory with the wrong or old "firmware".

I'll keep y'all posted but it seems like there could be a factory firmware issue out there. We will see!
