Welcome your new Ecodiesel with GDE. Seriously. You will then be turning off the EGR electronically. It will be there but your oil will be clean, the intake clean, the swirl valves clean and no heating up the intake. Then you also get to turn off the DEF sensors and stop those problems. You can then use water instead of DEF fluid. Pilot injection is now off, better fuel mileage is now on and more.
It is a real "no-brainer' for longevity, cleanliness and reliability. Of course you can physically rip everything out and replace then total exhaust, cutting off the sensors for a full delete. Then you need a program to make it run. Guess what??? GDE. Just do it.
