i was just wondering if any one has had any experience with the tornado fuel saver. I heard that it is suppose to increase gas mileage by 2-3 MPG, but also to increase horsepower by around 10 HP. Some people have told me that it isn't worth it and it might make it worse(because i'm putting it in a 2002 bravada, with a 4.2 I6), but some say the opposite. just want to see what u guys think about it...thanks!!!
