If your car has EGR, please keep it operational !
Better mileage at the expense of polluting MORE is not my idea of driving more environmentally friendly.
Maybe you can support that claim. All that I've read about NOx is it requires hydrocarbons and UV to create smog. Modern pollution controls have reduced vehicle HC output to the point that additional NOx control is pointless.

Even so, if I net 10% better mileage with the disabled EGR, my total pollution output with biodiesel is WAY ahead. Additionally, I don't have to clean out my intakes anymore. Bonus.
