EGR VALVE

I just made a solid gasket to put in between the valve and the intake manifold. Then I put caps over the header port and the EGR valve inlet (you can find them on Ebay). That way you can leave the valve plugged in and not set a light. It is true that you can get some mid load knock without the EGR, but if you can chip your car then jsut disable the EGR entirely. It will hurt fuel economy a bit, but it will keep the intake and heads a lot cleaner. One of my fellow calibratoers stated it well: You shouldn't feed an engine it's own S$#t!

I have my EGR deleted and havn't had any knock issues. This is the first I have heard of that being an issue, but that doens't mean some people haven't experienced it. Every car is different even the same year, same mods can have different results.

I run premium fuel in mine, slightly advanced timing and have not had any problems with knocking through out the RPM's.

Good luck!

You can make a tube from soft copper tubing found at your local
hardware store without too much trouble

I did it myself and it really wasn't all that bad

Like was said above

The correct way to not use it is to tell the pcm it is no longer in use

Yes ... you can take it off ...
Yes ... you can disable it mechanically ...
however
When you do such a thing ........

You run the risk of ping issues

The GT Stangs have very high spark and lean mixtures at light/mid
load conditions

therefore

such egr removal methods can very well cause the ping thing to
rear it's ugly head

Cobra Stangs are not quite as bad as the GT's due to different spark
and fuel settings but still ... same thing might happen to them as well
