Running the engine without egr will only make it run better, or at worst, no change. I removed the egr on my 89 long ago and has no effect. Same with all my other vehicles it was removed from. Your check engine light will come on.
What does it mean to "tune out" the EGR? Is disabling the code all people do? Or do they make changes to the PCM calibration?
On the other hand, my truck threw a CEL for inadequate EGR flow, so I'm not sure if the computer is smart enough to know the EGR isn't working and doesn't make those changes or what.
Even if you don't notice it running any worse with the EGR deleted and no tune, it certainly is.
