I have been reading all the stuff about "black boxes" and the like. My Question is has anybody with an ez or any other chip gone in for warranty work and been denied because of a "electronic trail" from the chip. I never had any trouble with my 2000 even with the comp and peirced wire but the dealer here is not very bright and unless the computer told him something was up he would never guess. So I am wondering if the computer has been upgraded for service managers that do not know anything.
