none unless you are disableing your EGR system, which again gains you nothing, possibly even hurting gas milage and performance

Disable the EGR and:

1. Your combustion temperatures will rise.
2. Possibilities of knock retard will increase.
3. Possibilities of burnt valves will increase.
4. Spark plug life will be reduced.
5. Fuel mileage will decrease.
6. Emissions will increase, possibly decreasing the life of your catalytic converter.

The ONLY time an EGR should be deleted on a daily driver is IF it'* supercharged AND intercooled.

OR if you have a tuner and don't care about half the crap I just listed.
