If you're going to have a bung welded on, make sure you get one first, I had a hell of a time finding one and none of the shops I went to had something I could use. Maybe the shops here just suck but to be safe, it isnt that hard to obtain one, apparently they just screw out of the oem header.
I originally had done the EGR Delete except for the tune, couldnt afford it. Had ended up throwing away the egr tubing & valve. Although I was able to find enough parts to put it back together, ended up costing almost as much as getting the tune would have.
I did however figure out that the egr tube from an 02 would work with the 01, I had read elsewhere it might not work but mine works fine.

|Blue5ive||I would like to know how much it is supposedly reducing temps since it is adding hotter air to the intake charge than ambient air temps. Only way I see it is if its reducing complete combustion of the mix.|

|sgtsmasher||i dont see how at all, that it helps with cylinder head temps...what the egr does is, from my understanding. taking a half and half mix of burnt gas and unburnt gas from the engine, and returning it through the egr tube, into the ufo looking thing then to the intake manifold. which in turn is getting sucked back into the engine...and from the ufo looking thing, there is small rubber hose that goes to a sensor.|

|2002FordFocusZX3||Deleting your egr valve will just give you worse fuel economy it only works while you are cruising anyway it is shut off at wot and idle and the egr also helps keep cylinder head tempuratures down|

|amc49||It may work, only about 3-4 psi there............DPFE mainly looking for the DIFFERENCE in pressures. I don't agree with the later O2 sensor failing inspect statement though, they would automatically make up for the extra air. Only by checking for NOx could it be found.|

|Magus2727||Interesting... not sure if it has. always thought the EGR needed to be under pressure....|

any one tried deleting the EGR but still having it??
IE the system is still there making the computer happy, but its pulling in air from the intake?
its a how-to for a escort, but the system is more or less the same...

You have to get a tune otherwise you will get an EGR low flow and excessive flow (forget the two codes). This will show that the EGR is not working and also show a check engine light which in all cases I know will cause failure before they even scan.
A Tune will disable the EGR reporting to "NA". Since the emission systems are "universal" and some vehicles have systems that others don't it only "fails" or flags "Not Ready". If it says "NA" or "Ready" then it passes.
Some places also do an engine check along with the ODB II scan. If they have looked at many focus they will be flagged off the bat that your cat has moved. so may take a closer look. if they see things not hooked up that may raise a flag. so if you don't use the EGR then it may be best to remove it completely, or leave it in made to "look" like it is connected.
All depends on how intelligent and out to get you attitude the emission shop employee has. Most people with a Tune never have a problem, however some have (such as my self)
