These discussions are very interesting, and my understanding to this point about the EGR function is that:
Having the EGR -will keep the intake much cleaner, helps control knock sensors and pre-ignition firing. Heats up intake flow which robs a little HP, helps with emmissions.
Not having the EGR - Engine intake gets dirty and buildup occures, hot gases no longer flow into the intake which allows for cooler flow and makes for a little more HP, reduces risk of vacume leaks, cleaner engine bay, check engine light comes on.
It almost sounds to me like it is better to have it then to not.. I was looking into ways before this discussion to keep the EGR intact with the S&S Header install. I was seriously considering removing the heat sensor that goes into the stock header/exhaust manifold and drill, weld and remount that same heat sensor in approx. the same location on the new S&S Header, in order to keep the EGR intact... JBrady had then mentioned to me that the EGR heat sensor has to be re-mounted onto the lower exhaust down pipe, and the mounting on the new header will not work (reads will be off or something to that effect) and if installed on the down pipe re-routing of some other crap will be necessary to make it all work..
The bottom line is that deletion of the EGR is only really necessary when installing aftermarket headers, and should probably remain intact otherwise. That is my take on it..... does that sound about right?
When deleting the EGR should that grime buildup on the intake be a concern after years of use?
