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

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.

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

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.

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.

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.
