What exactly does EGR delete mean?

[Drew11474]

I just bought a 2010 6.4 and I was under the impression the best thing to do to improve the life of the motor and MPG's was to remove the DPF filter, get some type of tunner/chip/programer, remove all components or bypass/block anything to do with EGR system (EGR valve and cooler), 150GPH lift pump and install a 4" turbo back exhaust?

I was just told by a diesel performance shop that all are correct but removing or bypassing the EGR components because the twin turbos on the 6.4 do not have waste gates and can cause head gasket/stud issues? I was told that the H & S mini max tunner would disable or turn off the EGR but will still allow it to act as a wastgate for the turbos to blow off excess cylinder pressure?

I guess my question is when I read about guys doing an "EGR delete" what exactly does that mean and what is the correct way of going about it?

Google is your friend in most cases, EGR, Exahust Gas Recirculation, ports "cooled exahust gas back into the Intake (along with soot). The EGR does act as sort of a Wastegate by design. Head gasket issues only if you make some crazy power.

Couple of shops I would highly recommend, Performance Truck Products, and Rudy's Diesel performance, both know their stuff and have worked a bunch of Ford Diesels. Nate/Eric or Gabe/Aaron will not steer you wrong.

Thanks for the reply. I dont plan on going crazy as far as power goes, looking more for MPG's and reliability but I do plan on putting the truck to work when I need it. I tow a trailer that weighs in around 14,000lbs when fully loaded but thats only a few times year. The rest of the towing is light and just a daily driver. I see listed you have a EGR delete, how did you delete the EGR, is it a bypass type, blocker plate or tuner disable? And what, if any problems/issues have you had with your 6.4?

I bought this truck on a whim because i couldn't stand the GMC duramax i bought also on a whim after my 6.0 blew up 2 years ago so my 6.4 knowledge is.......well not much yet but I do no it is very similar to the 6.0 in many ways?

The egr delete consist of removing the two egr coolers and the egr valve being replaced by an 90* elbow. Deleting the coolers is a good idea to eliminate the possible rupture of the cooler tubes which in turn could possibly leak into the cyl.

All the knowledge I had gathered over the past year makes everything you are telling me dead on accurate so when I was told it was a bad idea it blew my mind? If it wasn’t already confusing enough to figure out which mods are right for me and which aren’t, I was beginning to become frustrated. There is no doubt in my mind ford makes a better looking and tougher truck (esp after owning a GM for 2yrs) I just want get it back to the day's of the original powerstroke and try to make it as reliable as possible.

I guess I will stick to my original plan of DPF delete , EGR delete, Tuner, Exhaust and lift pump.

Thanks alot for the help guys and anything else I'm all ears!
