Do not remove the 2nd baro sensor that is behind the fuel filter. It only needs to be electrically connected so the ECM can "see" it. If you remove it you will get a P2227 baro sensor code and your performance will suck. There is no setting in EFI that I'm aware of that will prevent this code should the sensor be removed (from Guy at SoCal diesel). If you remove all of the other solenoids, there are more DTC MIL and test enablers that needs to be set to "Not reported." They are: P0401-P0409, P0489-P0490, P1404,P2141-P2145.
Also B1501 to 300, B1504 to -39 and B1505 to 151 to disable EGR function.
That should do it.
If you are not running a big tune, simply disabling the system is sufficient to stop EGR function since it takes 20lbs of boost to overcome the spring of the vacuum operated EGR valve. Its the cheapest blocker plate you can get. Try this first before you drop coin on up pipes and stuff to remove the cooler. I left my cooler in place along with my EGR valve. Only thing I removed was the pump and solenoids and saved some money in the process.

Fuel mileage? Who cares, its a diesel.
