Message: I just purchased a 03 Quad Cab Dakota 4.7L heavy duty service package. I've been ranging between 13-15mpg depending on how agressive I drive it. I've been researching aftermarket parts that add HP and increase MPG, are these just gimics or has anyone had any luck with them? IE Tornado; Cold air intake; ect...
Message: Good luck. If you find something that actually works it would be great to hear about it. Considering you are driving a 4000lb vehicle the mileage isn't that bad. I avg. about 15.1-15.3 every tank.
2002 QC 4x4 Sport Plus, 4.7L, auto, Patriot Blue, Tire & Handling group, Heavy Duty Service group, Leer cap w/out windows, Mopar Step bars and roof rack, Rhino liner in bed and on step bars, Pace Edwards Power Tailgate lock 3.55 rear, 4-wheel anti-lock brakes, all possible fluids are AMSOIL
