Hey folks,

I have a 05' Excursion with the 6.0 in it. I use it mostly for highway travel and towing my 32' travel trailer (about 10000 loaded) and my family.

It is currently bone stock and I would like to turn it into a reliable, fuel efficient towing machine. To that end I plan on:

• EGR delete (don't know which ones are better then others)
• AFE intake/filter
• 4" turbo back exhaust
• would like to install an exhaust brake as well.

Unsure if the follwing are needed/important:

• New ARP studs (heard these are crazy expensive on the 6 liter)
• chipping (dangerous without the studs)
• Transmission mods
• FASS fuel system

Any suggestions would be appreciated.

 

Do NOT remove the stock air intake system...you already have the best.

No to the exhaust brake and to deleting the EGR. Newest info suggests that removing the EGR leads to more problems than it solves. YOu MAY want to replace it.

OK to the 4" exhaust.

 

What problems is removing the egr cooler causing?

 

Wow, I have never heard/read any of this?

 

Sorry this is wrong. What evidence do you have to support this?

 

Check this thread out:

It may not lead to more problems, but like the title says there are side effects on the '05+ trucks that are worth thinking about IMO.

 

And this one....use your own judgement!

OOPS...same one Steve just lead you too.....

 

I am aware of the issue cheezit presented. I just don't think its accurate to say that "Newest info suggests that removing the EGR leads to more problems than it solves." Cheezit presented ONE issue with cooling fan operation. This problem can be solved with proper tuning.

 

Removing the EGR doesn't really solve the culprit of the oil cooler as it is typically the oil cooler that craps out and when that craps out it takes the EGR cooler out with it.

Reason for most of the repeat EGR replacements during the "early" years of the 6.0 is that techs weren't aware of the connection between the two coolers, so they would fix one, but because they didn't fix the oil cooler and it was still "broke" that caused the second EGR cooler to go.

Also one problem that removing the EGR system could create for you is problems with the Fed. It is against federal law to remove any emissions equipment that came on the vehicle from the factory. Whether or not you have emissions testing, it is still against the law. Now you may never get caught, but if you travel with that vehicle extensively you are playing "russian roulette" on when/if you get caught.

Also there is anecdotal evidence that suggest that there could be a loss of MPGs by taking the EGR out of the equation. A lot of custom tuners(people) write tunes with the EGR still operating unless specifically asked not to. To some that may also be a problem.

Bare in mind that I have ~200k on my truck, have both original coolers and I'm putting down 508 horses at the rear wheels. I have a hard time at believing that the EGR delete/bypass is the way to go.


I wouldn't do any a/m intake. They don't flow more air then stock until you are way up the RPM range and that's not usable for a stock or just tuned 6.0. Also filtration of a/m intakes has been shown to be less then stellar.

As far as tuning goes, it is far better to go custom. Both a better experience for you and better for your truck and tranny in general. Also with custom tuning you can have a tow program that makes your turbo act as an exhaust brake. Pretty good for those "heavy" loads. I would really only use it for loads >=5k.

 

Thanks!!!

Would there be any issue to upgrading the EGR and cooler?

 

Not that I know of......

 

guys for what is worth at some point odds are I will be reinstalling an egr cooler. odds are it wont be fords. Imo if I had it to do over again I would be looking at an aftermarket cooler. all in all the trucks run good stock
Im not not endorsing anyones products so....

 

Saint_Michael...The best thing to do is to check out the tech folders. There is a ton of great info in there. Maintainence is key with these rigs and not cheap. If I found this forumn before I started my mods I would have done things way differently.

1st I would take care of any upgradeable mods(meaning turbo drian tube,fuel pressure spring kit down to fog light mod to doing the zoodad mod ect..) Most of these mods cost little or nothing. There are so many things to look at, but all seem to have working wonders about them.

2nd would be gages or other means of monitoring what the parameters of vehicle are doing. Extreamly vital...

3rd I would look in to Arp studs. These are around $500 to $600 maybe cheaper. ( If you are going to run tunes)Alot more to put them in....

4th I would do some custom tuning. Currently I use the Banks 6 gun/Iq.
I bought that well before I knew about this site. I'd like to say that I've had no problems but, I've been through 2 sets of HG,s egr and egr cooler. More than likely due to having tuner before doing proper mods 1st.

Thats just my way of over thinking things. I did not mean to freak you out at all. YOU CAN DO THE EXHAUST AT ANYTIME. Depending on where you live you could kick the kitty and ditch the muffler. Warning... This gets very loud and scares the crap out of people, sometimes even your self. My exhaust is in the manner of 4'' straight dumped before axle. (STUPIDLY LOUD) You should not need larger than 4'' unless your going to make mongo gobs of power.$$$$$$$$$$$ on top of the $$$$$$$ you spend in taking care of it.
I hope all this helps u out a little. Start with doing alot of routine maintainence. Oh yea, cooling system flushes are a must. Do that and throw on a filter set up from dieselsite. The kit is somewhears around $130. A smart investment(PREVENTATIVE MAINTAINENCE) hint hint
ps my spelling is not so great

 

I wasn't aware that custom tuning had fixed the problem with fan operation parameters of the newest Ford flash, even with the EGR turned "off".

 

Thanks folks. This has really changed my outlook.

To summarize:

Exhaust Good
A/M Air intake not required
EGR can be replaced with stouter aftermarket, doesn't need to be deleted.

ARP Studs are good, but are they not quite expensive to install on the 6 liter?
