I too read on this page that disconnecting the EGR on the Cali-versions doesn't have any affect. People with other cars claim they get improved fuel economy and quicker accelerator response. My car is already pretty quick, so I don't care about acceleration, but I feel better knowing that exhaust soot isn't being thrown back into the intake manifold. Unplug that EGR!
