V6 Fi Vs 318

With headers, 390 cfm 4-bbl and 2.76 gears out back...I'm able to get 22-23 MPG consistently. Most of my driving entails 65 MPH highway speeds to and from school at about 2600-2700 RPM. 17 seems pretty low. My slant likes the higher RPM's as well so I usually shift it myself. I also agree with Grinder, wheels/tires can wreak havoc with performance. I put wheels on my Dart that were 2 inches wider, and immediately the 1/4 mile times went down 4-5 hundredths.
