[Ni87]

I don't know. I'm still pretty young and inexperienced. But everytime I've deleted the egr my engine has stayed cleaner and my mileage has increased. On my 87 Nissan I'm not sure how much it increased but doing the delete on my xterra gave me an extra 3 mpg. Now that I have this untampered Honda and a little more knowledge and experience I can do some more testing. But I understand your theory. From what I've read egr is just to decrease compression temperature down to reduce Nox or something. I'm going to test it within the next couple months. Try to set it up so I can do a Aba test.

The only trouble reading about this stuff is a lot of information on the Internet can be misleading from all the opinions and hear say. Only good way to figure it out is to test it and get personal experience or find more factual content. I'll have to get an afr and egt gauge to really prove any of the "known" egr facts.
