The EGR tube will not really affect your MPG, and your shift points are just
fine as well.
After the O2 sensor, I think the biggest culprits to poor mileage are:
- Bad MAF ground.
- Bad or misadjusted TPS
- Bad ignition system components (wires, coil, cap, rotor.)   If you are
using the platinum plugs, those are most likely OK

Maybe look at your fuel filter, reset your ECU, clean your TB, replace your
PCV and check for vacuum leaks if you are still having MPG issues.
