SCT Tuner repace need for EGR delete?

[BearDZ]

So I was planning on deleting by egr when my warranty expires this year and am told that I can just turn it off with the sct tuner, which I would want anyways if I was gonna delete the egr to eliminate the codes that the egr delete would throw on my '06. So if the sct tuner can shut off the egr, do I need to do the egr delete? Never mind.....I called and got my own answer. The tuner just turns off the throwing of the code.

put a cooler bypass on mine and it never set a p0401

leave the valve there and functioning. it's not going to hurt anything

What is the reason for doing the EGR delete? I am new to tuners and saw this option on mine but I'm not sure what it does. Can someone explain what the EGR is and what it does and then why you would want to delete it. Thanks!

EGR= Exhuast Gas Recirculation. Takes exhaust from your up pipe and goes through the egr cooler and sends it back in your cylinders to get reburnt. They can fail can cause problems

Ok, so I will try to give you the short and sweet explanation for the EGR delete. The oil cooler feeds coolant to the EGR gas cooler. When the oil cooler plugs up it starves the EGR cooler for coolant and that causes a terminal failure in the EGR cooler. Now that your EGR cooler is leaking coolant into the intake or exhaust manifold of your 6.oh your chances of a blown head gasket or hydro locked engine go up exponentially. The root cause of this is the fact that Ford Gold coolant is junk and breaks down and causes these system failures. You can flush your coolant and change to a Caterpillar extended life coolant with an EC-1 rating as well as unplug or turn off your EGR system. This will solve the coolant problem and limiting the flow of EGR gases through the cooler will help prolong the inevitable. The Best plan is to get a monitoring solution like an Edge Insight and monitor the difference between the oil and coolant temp ( Delta ) then start saving to replace the oil cooler, STC fitting and delete the EGR cooler. That should cover all the high spots, however there are a lot of other finer technical details that others can fill you in on. The search button is your best friend in this case.

Would there be any harm done in unplugging the EGR valve, blocking the code via the SCT, and then welding up an old EGR so it can't be blown open in any way?

Here is a thread on this subject. It's up to 19 pages, but worth the read for the first 6-8 pages,

Do you have your EGR valve plugged in and operating properly?

I have a 06 and got the cheapy 120 dollar kit off ebay. Comes with a cap for the exhaust pipe and then the typical U piece that goes fromt the intake to the engine.

It through a code on my 06. My buds 05 it didnt. We both didnt touch the EGR valves and left them plugged in in both kits. IMO leave the EGR where its at.

Yes I do.

I'm leaving things as is for now. I moved to Clark County Wa. and we have some emissions testing. Currently it is just a "snap" test, not sure what the future brings. The Cat comes and goes, strange how cats will do that.

I bought my 04 in summer 09 with 28,000 on it. I have read so much about maintenance and different things that I'm hoping it will survive better than when they were originally sold.
