EGR removal?

What problems may come when you remove the EGF, and how to use it wisely deleted?
Does the PCM programmed again or do any other updates while EGF has been removed?

The EGR valve or the EGR cooler? Or both?

It is customary to include some background information about the truck (engine year, mods done) your asking about. Different years of manufacture have a few differences between them that can effect the answer.
I will give you the generic 'cover it all' answer.

First, Deleting the EGR cooler will stop the flow of exhaust gases into the intake. The intake should be cleaned as part of the install, though not absolutely necessary.
Installing an EGR cooler delete can take the inexperienced 'back yard' style parts swapper a full day.
Post install, I recommend leaving the EGR valve in place (and plugged in) in the intake. Since the EGR cooler is deleted, the valve is doing nothing. There is some evidence that removing the EGR valve can cause some issues with the cooling fan turning on at the proper time.
Having an EGR cooler delete will result in a "check engine light" on some year engines. The 05 and newer engines will likely get the code. There is a way around getting the code, and that is to purchase a tuner with the ability to delete the EGR valve commands along with a custom written tune. The SCT "X3", "Livewire" and their "Touchscreen Extreme" are very popular tuners. The tuners loaded with custom tunes cost in the 400-1000 range, depending on what style of tuner you want.

There are other EGR delete kits that are of good quality that are not as much money. CLICK HERE for one that will cost about half of the one you linked to.

It is recommended that you know what the condition of your oil cooler is previous to the EGR delete install. You need to know the temperature differential between your Engine Oil temp and your Engine Coolant temp.
To be able to access this information requires gauges. The electronic style can access the existing sensors in the engine. Before selecting an electronic gauge set, you should decide on which tuner you will buy since some of the tuners are also electronic gauges.
To test the temperature differential (delta) you would take the vehicle out and get it up to normal operating temperature. Coolant temp should be 190F or very close to it. Set your cruise control to 60-65 MPH on a flat section of highway, run it for 15 minutes or so and keep an eye on the temps. Should your oil temperature be 15F or higher, that would tell you that it is time to consider changing your oil cooler. The oil cooler can become clogged on the coolant side of it (it is a liquid/liquid cooler). Once that clogging gets to the point of impeding the flow of coolant the oil temperature climbs. If ignored, serious engine damage can occur.
The reason to check this previous to an EGR cooler delete is because installing the EGR delete requires the engine to be torn down very close to the point where the oil cooler could be easily accessed for replacement.
Prior to installing the EGR delete it is also recommended that you flush and clean the cooling system of your truck. There is a document that I have a link to in my signature line that will explain the flushing process and teach you how the whole thing works. Click on the "nylyons' "reverse flushing" technique link in my signature line for more information.
To self-install your own EGR delete and change the oil cooler, I have another link in my signature line that will show you step by step what needs to be done and there are also tips, tricks and a few suggestions in that posting. Click on the "step by step EGR and Oil cooler replacement" link for more information.
