Is that because there is more vacumn free'd up since the egr is deleted? Or is this a different problem I should be worried about? Gas mileage is about 25 mpg at 70-75 mph. I do plan on getting a tuner and deleting the egr function/turning is off and am wondering if this will get rid of the map sensor problem?
