Back to the gearing question, assuming gear ratio X costs the same to manufacture and install as gear ratio Y, which it should, why would Chrysler engineers completely ignore a practically free method to increase both performance and mileage?
Who knows why manufacturers do what they do? I question a lot of things from the factory.
Have you ever changed gears in anything before? It makes a big difference. I don't know why the manufacturers choose what they choose but we can definitely make it better.
