especially on a fuel injected vehicle there is no advantage and some disadvantages to removing the egr valve. first off the ECM is programed for it to be there so removing it will cause problems with running based on that alone.
The reason I ask is there is a company that makes a kit for efi vehicles to fool the ecm. I was wondering if anyone has acually used the kit and if it was worth it. The kits are fairly cheap.
It might fool the ECM OK, but, does your engine use knock sensors? EGR can reduce pinging and detonation, allowing more aggressive ignition timing when conditions allow it. Not sure an '89 uses that type of system, but I'd:
--research that before I changed.
--make sure my mods were easily reversible in case it made things worse.
That is why I am asking if anyone has any experience with the kit. This is my research LOL. That is also why I asked if any one knows a good Ford gear head site. It runs great but heck there is always room for improvement on these 460 either in better mpg or better power.
