Is a EGR Eliminator Plug necessary?

Post by shelb94 » Fri Sep 14, 2018 5:53 pm

I have a 1965 with a 1990 5.0 efi. I've removed the EGR valve & spacer. Is it necessary to use an EGR Eliminator Plug (ex:LMR product# LRS-9428A EP) to keep the computer running properly?

No. With the computer not using the position sensor or trying to control the actuator, there's no need for any kind of fooling-device.

Those are only necessary when you have to run the stock tune and you don't want the computer to know you've deleted stuff since that logic would be active on a stock tune. When you are forced to use the stock tune to conform to some racing regulation, then you have to use stuff like this along with a MAF calibrated to your injectors in order to fool the computer into running the engine while it believes you still have stock injectors.
