I been reading this forum almost daily now since I got a Ford 6.0 L truck which is my first Diesel.

I would like to beef up my 6.0 L some but keep it legally and I have a question about the EGR cooler.

I am aware that there are EGR delete kits but I rather keep my EGR value intact in case I decided to resell it someday but I would like to try testing with EGR value disabled some day to see how the stock performance and MPG are.

Since I wanted to keep EGR value in so I was thinking installing one of those aftermarket beefer EGR coolers which from my understanding they use stronger welds and pipes in those coolers.

And if I unplugged my EGR it will stay closed like it was deleted anyway correct?

But I have a 2007 F350 so I will have to get custom programming to prevent it throwing a code correct? I still want the EGR to function normally when it plugged in but not to throw a code when it unplugged.

Is there such a custom code to keep it stock but disable the EGR throw code only?

And what aftermarket EGR cooler would you recommend? I am thinking I might get one of those kits where it come with oil cooler as well too and do the whole thing at same time.

Thank you for feedback

From what you describe, you want a Bullet Proof Diesel EGR cooler installed. (Going this route will not require a tuner since it will not throw code, and your truck will be "legal" for resale anywhere)

When you see someone say EGR delete, it's really an EGR COOLER delete. ( people forget to put the word "cooler" in there) The EGR valve itself is not what causes problems, the cooler is. If you unplug the egr valve, your engine cooling fan will not operate correctly.

EDIT: I probably misunderstood....do you want a tuner for increased performance?

 

You better off putting in a BPD EGR cooler and if you want
to keep the valve closed and are thinking of programming
look at the link in my signature and get a SCT tuner from Matt
at Gearhead. They can set you up with some good programming
and or go with basic SCT unit and just turn the valve off.

With that said, definitely do some research before you buy what you want. This place is great for that

 

I have a BPD cooler, and the oil cooler could plug right off and you wouldn't hurt the thing. TIG welded tubes, very stout.

 

The main reason for the EGR delete is to keep it from leaking coolant into the engine and causing stretched head bolts and head gasket failure. The second reason is to eliminate the soot from the exhaust getting back into the intake flow and getting deposited on sensors and speeding up wear. I don't think there is a significant power improvement or mileage increase.

There are several suppliers of the EGR cooler on the net now and prices and workmanship vary. I went with the BPD unit right after I got the truck a few years ago before seeing the other suppliers and although the price is a bit higher it will have a serial number on it and have a lifetime warranty. I don't want to change it out but it's worth something to know they back their product.

The Ford oil cooler kit is the way to go in my opinion. If I understand correctly, the BDP oil cooler (in the kit) is a little different design. In an effort to to reduce clogging on the coolant side there are larger -but fewer- passages. This has a slight effect of reducing heat transfer from the oil to the coolant, EOT's can run a bit higher. Clogging the oil cooler shouldn't be a problem with a well maintained cooling system, and a filter is a great idea even on a clean system.

The EGR valve is one of a few devices on your truck that is not only receives commands from the PCM but reports it position back to the PCM. I've read under certain throttle/rpm/load situations it can be physically opened by airflow. I haven't witnessed this but it seems possible to me. If that can happen, just unplugging it may allow it to be opened when it should be driven closed. Also the missing feedback from the valve can result in the PCM not knowing the parameters have been met and the cooling fan speed should be increased.

You'll want a tuner on your '07 if you want to disable the EGR flow. No matter how you do it. The PCM monitors the IAT2 sensor (Intake Air Temperature) and watches for an increase when the valve is opened to confirm flow is happening. Some of the earlier trucks had a software version that allowed for the valve to be unplugged without turning on the CEL but there was still a code stored in the PCM. The tuner will make the PCM ignore the missing feedback from the EGR valve and IAT2 or substitute a value for the missing values.

Certainly, putting a new oil cooler in there isn't going to hurt anything but I would suggest getting some type of OBD monitor to verify the temperature difference between the oil and coolant temps and verifying the cooler is needed.

 

One thing I was told about the way that some of the tune
writers do this is by wiping out the EGR table. This way
no mater where the engine is it will always be commanded
at 0% EGR open. The PCM will still look to see if the valve is
still there during the pre-start test phase.

Another option for those with the square cooler is to replace it with the early OEM Round Style and swap out the up-pipe with the early style.

Keep your cooling system and oil cooler clean and up to snuff and you don't have to worry about the egr cooler.
