egr delete pros/con

Okay so I talked to a ford diesel tech and he said DO NOT put a egr delete on these trucks it will mess them up quicker that sh!t through a goose. he said blocking off everything off makes the motor get to hot and there is to much pressure...is that just the "ford tech" talking or is that what the case is? cause ive just got this truck i was pretty sure of doing an egr delete after doing all the reserch but now after him saying that im just not sure. what do yall think??? thanks alot guys!

Pros
- no more hot, sooty exhaust gases going back through your intake.
- cleans up the engine bay
- eliminates the possibility of a cooler cracking and hydrolocking your engine

Cons
- you loose warranty if that's important

Probably more pros but that's all my mind is letting me type right now

OP, That sounds like a case of an ignorant man not wanting to admit he is ignorant. There is no cons to doing an EGR delete UNLESS you live in an emissions testing state. And then the cons is very obvious

I think he was referring to the issue of deleting the egr creates more drive pressure which is why the high hp trucks have waste gates. They say with stock truck tuned and egr and dpf deleted the pressure isn't enough to hurt anything. It's when you get more air and more fuel is when the need for waste gate comes into play. I'm also on the edge. Haven't decided what I'm gonna do just yet

My questions are: if you're deleted, obviously you're running a tuner of some sort. Is the EGR a separate selectable option to delete? It has been my understanding that when you delete DPF you are also turning EGR OFF. So, what is the difference if EGR is turned OFF versus not there at all (besides the actual coolers themselves)? If EGR is OFF, the valve is ALWAYS closed. If the EGR is GONE, ports are blocked off...same as valve being closed (not allowing exhaust back into the intake).

Mine is coming off the first chance I get!!!

Deleting the egr doesn't create more drive pressure. What happens is the drive pressure can over power the egr valve and push it open utilizing it somewhat as a wastegate, but like stated, only with more fuel should you have to worry about drive pressure. And even at that point you are still best to remove the egr coolers and install an EGR delete w/ wastegate. The tech should have mentioned that if he knew what he was talking about.

The difference in it being turned off vs being removed is mainly the coolers are still there with it turned off and the heat still flows through the coolers which can still allow for cracking and coolant can fill them up.

wow I got tons of great feed back. as of right now yes i am still under warrenty. thats for another 9k miles or until like september sometime. anyway, I want to get that dpf off of there like now i cringe everytime the truck goes into regin mode while im drving just because i know exactly what its doing under the hood.

But back to the EGR problem...this tech was very adimit on not deleting it for the reasons i had listed. But i do plan on keeping the truck a while and want to prolong the life of the engine. and by the time i figured out i had a cracked cooler wouldnt it be to late? damange would be done wouldn't it. versus doing a delete and just not having to worry about it. and im not going to be running any high fuel stuff the truck is not a sled truck just a daily driving trying to get way better mpg. this is why i like this website!!

So in saying that about the added fuel and big power increase about the drive pressure...it would have to be way more power than the higest tune on say a Spartan (being it has the highest power increase preloaded tune I've seen so far) to worry about a wastegate when running a complete EGR delete.

Pardon my ignorance...I'm learning diesels AND turbos all at the same time! Not only that, I'm trying to make sure I do everything I can now, to keep me from splitting that muther open because of something I could have done but didn't!
