Thanks for the reply. Don't take these comments the wrong way, I am just trying to get more information.
First off, I totally agree on boosted motors that EGR along with PCV would be good ideas to bypass or remove. It helps stabilize boost through the RPM band since it is a function of vacuum and EGR uses vacuum.
Next up, everything I have read about exhaust gas recirculation states that this actually helps to LOWER cylinder temperatures. Therefore by removing it, you are raising the temperatures. This would result in a leaner condition, which can help make power, but as we all know TOO lean is dangerous. Generally speaking, most vehicles, especially ones in the early 90s, came from the factory VERY rich.
Lastly, the ECU will NOT be able to change and trim the A/F properly after EGR removal. You are 'fooling' the ECU by placing a resistor inline. The ECU acts as if the EGR is in place and functioning properly, so there is no way it is adding more fuel for the hotter cylinder temperatures.
Don't take these as dismisive, I know plenty of guys on here have been running these motors hard without EGR. I'm just having a hard time seeing exactly what the benefit would be especially since the EGR has no effect at WOT. Also the EGR valve acts as cooler, so I think there is a misunderstanding that HOT exhaust gases are being dumped into the intake. While they may be warmer than cool air, their not that hot, and also the system is designed to lower cylinder temperatures.
