Hello again. So, I'm not trying to be picky, but the one thing I learned during my search was that to "only trust a GM Remanufactured rebuild." I've been that road. Question, what would be the "crazy" price for an NOS ECU if one were for sale? Just curious. Probably a hell of a lot more than "reman." Anyway, thanks for your response...
No it's not new and I'm not sure if it was ever used before but it has the GM stick around there saying that it was remanufactured and no it does not have a box. I hope that helps
