Hold up. I'm not saying that removing the EGR is going to give you that kind of MPG's.
Just stating that I have never witnessed the EGR hurting MPG's when it was deleted.
I have messed around with my car over and over and over to get the MPG's where its at.
Low gears do have a down fall on the highway(RPM wise). But they also keep the engine under a lighter load, which requires less fuel to power the car. With a higher gear the engine has to work harder(load) to accomplish the same as the lower gears.
