Yes I believe you are correct. One of the reasons we with older cars seek to improve our ancient EGR systems.... or in the case of the OP... to ADD an EGR system
EGR systems when they were put on cars initially was to pass emissions more than improve fuel economy... In today's vehicles the computers are much smarter about using the EGR system and much of the time it will improve FE as a secondary benefit.
