Waj,
I've looked into this a little more and stick with my original opinion of don't do it
I'm posting a couple of articles explaining EGR's, how they work and purpose etc .
Understanding EGR Systems
EGR Systems: Operation and Diagnosis
The biggest problem I see with what you are suggesting is that you would have to have various maps re-written or erased, you would also need to address any emissions control maps that may put the car into limp mode as the OBD II Emission standards have been breached.
Then the MAP sensor in the IMRC valve will be giving abnormal readings as it also contains the second Air Intake Temperature sensor, (the first one is in the MAF sensor), this will alter fuelling, possibly swirl volume and the overall temperature of the mixture.
Unless Fahad can get elite to look over the maps and see if it is doable and this I would also imagine would need a couple of rolling road sessions to ensure that everything is written correctly, which I would imagine isn't going to be cheap, then each year your going to have to take of the blanking plate and re-map to the old maps.
I understand where you are coming from, but I really am not sure whether this will cause more problems than the initial problem that is trying to be avoided by blanking it off.
One final thing as the EGR introduces exhaust gases to reduce the overall combustion temperature, then it would follow that with the EGR disabled the overall combustion temperatures would increase and in the article posted above it mentions a couple 100 degrees, I'm not sure what effect this will have on the valve and seats as they will be exposed to far higher temperatures than designed to operate in.
I personally think it is too tightly designed into the whole running of the engine to be removed without serious issues, unlike say de-CATing
That's my take on it, sorry
By the way did you change the Chamber comp Vacuum on the EVR and did you notice any differences?
