Ring and Pinion change
Has anyone changed thier ring and pinion to something in the 3.55 range?
Love the PSD. However, given that I only tow a 2,500 # trailer down the interstate on the weekend, I'm sure the 373's are costing me some significant MPG.
Someone posted on another site that a reduction from 2,100 RPM to 1,800 RPM could be good for 3 to 5 MPG. (Theory based on math not actual data.)
Could the speedometer be adjusted with such a change?
Thoughts?
