Don't eliminate EGR unless you can turn it off inside of your computer. If you do elminate the EGR without turning off the EGR funciton in the computer, your computer will still be boosting timing to compensate for the EGR gases in the intake charge which aren't present any more; that can lead to pinging. The cosmetic value, especially on a Fox Mustang is minimal.
My EGR is gone so is everything else. I didnt turn it off at the computer or anything. What I did was fliped the spring inside of the EGR plug and shaved all the extra plastic off and plug it back in this way the computer thinks its still there. You can buy the different plug on ebay do a search on here and you'll find the link to it.
I eliminated my EGR as well, but have yet to turn it off in the computer. Could that cause some drivability issues? My car will just turn off for no apparant reason, as if i turned the key off. Any input is very welcome...lol. Thanks.
