Do I keep this?

I'm starting to think that the egr. valve on my 89 cherokee 4.0 is'nt all that nescessary.Do all you guys still have yours hooked up?If so ,why?Should I get rid of it?why do the newer xj's come without egr?Thanks,this board is killer!!

I have keept mine working. the reason the newer hos don't use them is in the cam specs and engine mangment upgrades.
