With the 2013 model year Subaru began using a different engine in its Outback than in previous models. Among the changes to the engine was a small bump in horsepower and torque. It may be too early to ask but, does anyone that may have had a chance to evaluate both Outback engines notice a difference in performance?

Uhh, a 1.7% horsepower difference should have the same
performance effect as a 60 lb weight difference. That's 8-9
gallons of gasoline....

...or cleaning (some of) the junk out of the back seat,

I wanted to know if a low and mid range torque improvement was noticeable.
Peak power and torque increased by 1.8% and 2.3%, respectively,
while displacement increased by 1.7% (2.457 versus 2.498 liters).
So, 'improvement' in specific output (hp per liter) is less than 0.1%.

The new engine's torque peak actually moved 100 rpm higher, so
it seems extremely unlikely that the new torque curve has been
moved toward the low and mid rpm range.

All new!!! ...but essentially unchanged,

You keep over 60 lbs of junk in your back seat?
Don't take the dogs to the drag races. ...or the Outback.

the way an engine responds to throttle input is about as
important on the street as anything.
More than anything else, throttle response depends on
gear selection.

...in a hurry? DOWNSHIFT!

Which engine (the short or long stroke) would you say
would have the better performance numbers?
The one with less fuel in the tank or fewer dogs in the wayback.

...performance = power/weight = languid/portly,
