In the little research that I've done, it looks like the COBB accessport is the way to go. Although for the Forester XT the maps don't seem available even. I'd have to look into it more. I was curious how easy it would be to port the tech over to the Subaru. I can see that if demand is low, it may not be worth the time/money.
It makes me sad though to try to pass someone that want's to be a jerk and they accelerate.
