Is Running Lean ok?

from the looks of my plugs I appear to be running lean. Is this going to hurt anything? Also, I don't have the EGR connected so possibly that could cause it to appear to be running lean even if it isn't. Anything I can do to change the lean condition or anybody else notice very clean plugs without the EGR? The white on the plugs just above the threads has also turned a bit brown as if it is getting very hot.

Hmm....my EGR is connected and my plugs with 30K on them looked excellent. Usually though, having no EGR will make it run rich. A little lean isnt bad, but very lean is. The best thing to do is get a chip that is programmed for no EGR

I have the same setup but I actually just put in an EGR. My car wouldn't even start and run because I had lean. I had to replace the damn temp sensor for it to stop running lean, it took me 3 weeks to figure it out and fix it.
