See if this makes any sense: my DD 8v71 Naturals have N70 injectors. I believe that N55 injectors are also available for these engines. Now, '55' is 21% less than '70' arithmetically. Would it therefore follow that I might get 21% more (better) mileage if I changed out to the lower rated injectors? Apples for apples, I cruise at 1400 RPM, so would I likely get 21% better mileage if I stayed at the same RPM using the N55 injectors? Does this make any sense? Thoughts? Thanks.

Would changing to smaller injectors save fuel?
