I have 2008 6.4 and tuned with H&S XLT Pro. The DPF has been removed and deleted with the tuner.
Ya know, I've been reading a lot about how we should really also remove the EGR system with a delete kit.
Is this really needed also? What of I do not do it and what am I risking by running with it?
How many of you have not deleted the EGR and only deleted the DPF? Does anybody know of anyone who's EGR coolers have failed them on these 6.4s?
I'm trying to decide whether or not to do the EGR delete and don't really want to .

 

I would like to hear some replies about this as well. Haven't deleted my EGR yet. Still deciding if I should and if so what's the best way to do it.

 

Good question. I'm with you guys and am curious too. Up here in Canada, I believe that the EGR deletion kit is about $1200.00 and approx. 6 - 8 hours to install at the diesel shop (if you don't do it yourself). So around $2,000.00. Is is worth it for a fair chunk of change???

 

Sorry, I might have been off on the pricing for the delete kits. I see that they on the net for under $200.00. I'll have to question the shop that I was talking too.

 

$1,200 is probably about right for a full delete with a wastegate. The kits without wastegate are a lot cheaper. Closer to $200

 

So who all is not doing an EGR delete and why did you decide against it?

 

Unless you're running high HP tunes and racing alot a wastegate isnt necessary.
Delete kit with intake elbow is only a couple hundred $ (In canada as well).
It took me the better part of a day to do it myself.

 

i'm too on the fence. Would prefer not to do it. I run the H&S egr disable no power or +80 tune and am easy on my truck (no racing). Truck runs awesome as is now just not sure if i really need to do the complete delete or not.

 

I want to do one but have been told not to do it without the wastegate by the guys at h&s and the guys at alligator performance among others. No matter what horsepower tune your running. I'm running the hot dam300 so that makes me a little worried about the drive pressure. Someone correct me if I'm wrong but since the mini max turnes the EGR valve off I'm not getting any soot in my motor so the only benifit of doing a full delete would be to be safe if a cooler fails? Is that correct?

 

Well, there are tons of us running no egrs and no wastegates. So that alone tells me its not 100% necessary, Im either on 275 or 300 and have no wastegate...

 

How long have u been driving with your EGR deleted without wastegate? Do u run the hotdam300 hard or do u drive it conservatively? What happens when u have to much drive pressure anyway? Does anyone know? Tell me why I need or don't need a wastegate?

 

Sorry guys, I don't mean to throw the rhythm off of this chat but I want to follow and need a couple of questions answered first.

1. With the H&S, is it ok to turn on the EGR delete so that the EGR valve closes and NOT take off the EGR Coolers (no delete kit)? Is it correct then that ALL of the exhaust would then run through the exhaust and through the turbo? being that none is going through the EGR coolers, then motor, etc.

2. Wastegates - They are located on the air side feeding the motor between the turbo and the motor intake. Correct?? The purpose of them is to relief the high pressure of the intake side when you take your foot out of the pedal. Correct? Why would you need to increase the size of the wastegates if you take your EGR Coolers out? Part of me says that it is it because more volume of exhaust gases are flowing throught he turbo, INCREASING the boost. That extra boost has to go somewhere, therefore bigger wastegates. Part of me is saying that the same amount of volume of gases are going through the turbo being that it's a combined total of what is going through the EGR coolers, then motor, and what is going through the exhaust normally. AND part of me is saying that I don't have a clue as to what I am talking about.

Again, I'm very interested in this info but nee to understand this knowledge to follow. Thanks! Are the wastegates after or before the intercooler?

 

1. Mini max automatically turns off the EGR valve so nothings going through there.
2. From what I understand the truck uses the EGR system as the wastegate so when you remove it by deleting your EGR system with a delete that doesn't have a wastegate that extra pressure now has nowhere to go. Correct me if I'm wrong someone.

 

I run spartan not h&s so the 275/300 on spartan. I get on it here n there, I can monitor back pressure as well so I have an idea whats going on. If you run wot and let off instantly you'll here the turbo surge, I avoid doing that but its not a common occurence for me.
That being said I will one day install a wastegate, probably when the time comes for head studs, up pipes and manifolds...one day.

 

You could be right because I did NOT seen wastegates on the air flow diagram. Would it then be right to say that the opening position of the EGR valve is dictated by boost pressure?
