I have a question? Ive read all this thread and i seem to understand it well and think its a great way to easily get more out or you car at a little extra mpg but i was wondering, i do a lot of motorway driving and mileage and would this method work the other way around? I have a 3.38 and if i could live with a little slower off at the lights and wanted more MPG then could i use a lower type diff to bring the rpm down on the motorway and save on the long hauls? Could this work? I have a second car for hard driving so dont need more torque from my bimmer.
