EGR DELETE help needed please
I agree EGR's will increase gas mileage, I have noticed that and totally agree. I also completely agree that on the Evo, the valve is shut during WOT, so its only really open at part throttle conditions. However EGR's do indeed have one negative side effect. Overtime, they dirty your intake manifold, and rob power by restricting the overall flow going through the manifold (they coat the walls of the manifold with black soot, which creates a lot of turbulence to the airflow). Ever check out a race car engine? You won't find ever find an EGR valve on one. People remove the EGR valves for the same reasons that people put on catch cans, to prevent gunk from clogging the intake tract..
finaly someone understanding my opinion to remove the egr... thank you...
yes i do. he's a good man.
i had a guy install cams and it was just a mess... i then went to a shop who in turn fixed the car. from start to finish it was a $1500 cam install.... and no car for 2 weeks.....
it is running great right now... thanks for asking....
I have some knowledge of EGRs from Nissan motors. With the adaption of VVT, as previously stated, the need for EGRs becomes moot as you can replicate the effect of EGR by varying the cam timing. From what I understand the IX motor with the MIVEC has EGR, is this correct and if so why?
Also EGRs do not usually effect power in anyway, the problem is usually it is connected to the exhaust manifold and can make it hard to get a new one or switch to a turbo manifold, again from nissan experience. But at no time has anyone on a Nissan motor experienced gains or losses from removing egr. It really does almost nothing except clutter the engine bay.

Most aftermarket manifolds just block it off, on the stock manifold its just more effort than its worth to remove it, and pointless to remove it since it offers no performance loss/gain. Like mentioned earlier, it is supposed to reduce NOx emissions at part throttle, and helps improve fuel mileage.
FWIW Cams wreak havoc with NOx emissions also.
Although I'm not a tree hugger, I do think its unwise to remove it for legal reasons, in some states they do check for its existance during an inspection, others don't as long as you don't throw a CEL.
The short simple answer is don't bother removing it just to remove it. But I wouldn't lose sleep over it if you put in an aftermarket intake manifold. as long as you can resolve the CEL light issues.

I agree, I am also not a hippy *****, but if it doesn't hurt you, and helps the environment, why not keep it on?
