EGR alllows higher compression, more advanced timing, and a slight reduction in the fuel necessary for every combustion event. Properly applied it may have even greater benefits in the future, but they are significant today, and in the early years of EGR (late 60s) many tried to disable the EGR and found the engines would hardly run.
