·Just bought my first Dodge, drove Fords all my life but the Dodge looks and feels good. I have the 360 Magnum with the Auto. and 3.55 Gears with 4X4. Getting 14 MPG combo driving, 10 MPG pulling 6500 lbs of trailer with overdrive locked out. Will the Mopar performance computer help with give me a little extra power? How about an increase in MPG?
