The driveability ALONE makes it worth its pricetag. My truck accelerates like a bat out of hell and gets about the same mileage stock (.5-1.0) improvement. If I baby it for a hundred miles and fill up, I can easily reach 20mpg handcalculated. Not bad for over FOUR HUNDRED HORSEPOWER on an otherwise stock engine. Sheesh, people.
