To tune or not to tune

Okay had my 2.0 xt auto forester 6 weeks now and still smile to myself when I get in every morning for the drive to work.

As stated on other posts I bought it for its flexibility 4wd etc etc,but while I'm sitting at the lights and can feel the that pulse from the boxer engine up through the seat,I cant help but think help  that maybe the exhaust note could be a little bit more like a Subaru like.

I certainly don't want it to sound faster than it is but then again maybe tiny remap,you know just to free up some more torque and if possible a little more mpg would be nice.

 My question really is this is there any possibility for my 05  2.0 auto to benefit from any tuning available.

Thanks.
