I have owned Subarus for several years, mostly WRXs. I finely decided to try a Legacy GT. I am really glad I did. It is a great car, having good power, and more luxury than the WRXs I owned. Subaru has done a great job on the entire design, and functionality of the Legacy GT. I have added a Stage one Cobb Accessport, and it changed an already good performing car into a really GREAT performing car. The added hp/torque from this programmer really changes the entire character of the engine, without cutting the mpg. It's the best $695.00 I ever spent!!
You could always wish for more power, but I guess that is what the aftermarket programmers are for.
