Better to run it. It will help keep detonation(some)in check and it wont hurt overall performance as it only is running at cruise and not WOT.
Plus it will make it easier for the thing to pass emissions.
Fuel calibrations are designed have the egr working . Unless you are going to do a serious tune of the PCM I would keep it.
If the thing is beyond repair, then by all mean bypass it.You probably wont notice much difference
