The function of the EGR is to let exhaust gas into the air stream.........displacing oxygen.........and thereby reducing the combustion temperature. It does not give the exhaust gas "a second opportunity to combust". Ideally, there is no available fuel in the exhaust gas to enable additional combustion.
The fuel economy benefit from discontinuing the use of the EGR is minimal. Nobody has been able to document it with certainty.
