Not surprised to see a positive result among the negative comments.
Depending on the mode of failure, we can expect both better or less mpg. Those now seeing lower mpg may have been running with less EGR and more NOx emissions.
If the failure mode is giving too much EGR, a new EGR valve with values within tolerance, better mpg may well result.
