I am not very good with cars but I understand there is a way to reset your gear ratio. My car is a 5 speed manual transmission and it seems to rev kind of high around 70-75. It usually is at 3,000 - 3,500 rpm or so around this speed. My car starts to red line at 7,000 rpms. Shouldn't the car be around 2,000 or 2,500 at speed around 70-75? If I changed my gear ratio I would be able to save some gas I suppose? Can computer chips change the ratio or do I have to do something else? It almost seems I should have one more gear and it would be perfect...
