A 5.7L HEMI is a gas guzzler by definition. That being said, I would od an add on here, another there, when I could get products on sale at AutoAnything. So, with this, and the K&N cold air system, throttle body spacer, Accel super coils, plasma plugs, and Magnaflow exhaust, I effectively went from an average of 13.5 to 19.5 MPG- in the mountains, mind you. The Superchips programmer worked in tandem with these, to give me the last three MPG average upgrade.
