Tuned or not, you will most likely see better fuel economy by using a WAI. A big part of it is that it will help your car warm up faster. It also helps that it recirculates warm air into the engine for a more complete but of the air/fuel mixture and a teeny tiny bit because it saves a little weight.

I 100% agree! Driving technique is the best way to improve fuel efficiency. I've seen nearly a 10mpg improvement mostly through changing the way I drive.
