EGR Delete

[navy34]

when i got blackbear to tune my 01 engine, he uses the 02 PCM/OS which already don't use EGR. there was no issue whatsoever. when i put my headers on, i just pulled the whole system out & got an expandable freeze plug to stop the hole in the intake

I have a bb tune as well, but I unplugged the egr harness today and I got an ses light(p0405). So I guess its still functioning? But if there is no long term effect on my engine, I don't really care about the light.

I was curious about the EGR delete too. Will it hurt performance or MPG if you dont have a tune?

The only problem with not having a tune to keep the light off is that if there is something else that were to throw a code you would never know. Thats putting yourself at risk IMO.
