Safe to Remove EGR System? I have a 98 SS. I just installed a LS6 intake on the motor and I DO NOT HAVE A TUNE. Just the stock tune. Will my engine be perfectly fine without the EGR system? I just need to know this, I already know about the SES light. Thats not a big deal.
Thanks

Have any of you experienced a mpg loss by deleting the EGR? I believe that's what it is designed to accomplish. By recirculating unspent fuel/air into the intake to give it a second chance to be burned. Thats GM's thinking with the whole EGR system right?

from what i understand its only purpose is to lower emissions, in 01-02 it wasnt necessary as the cam was slightly smaller and emissions requirements could be met without it. i have deleted air and egr and have experienced no mpg loss with all the mods in sig. it stayed pretty much the same, i am hoping it picks up some after the tune though.

I deleted mine when I had my LS6 manifold installed. I also installed solid motor mounts. The total weight of all the stuff I removed, old mm's, air pump, hoses, nuts, bolts, etc. weighed about 55 lbs. the new motor mounts weighed 18 lbs. I saved 37 lbs.
