I was going through this limited T I got over the weekend sorting the parts out and I found 3 chips. The one in the computer has no markings at all. The one I found on the floor had a little hand written tag on it reading (turbo L/2). The third one I discovered on accident when I was pulling out a tape player that did not belong in the car. When I got it unhooked and went to set it down it rattled. I opened up the tape door and out fell a chip. It was an ATR Pit Bull 137 R3 or something like that. I found a 1999 ATR catalog in the trunk and found all the specs of that chip but I don't have a clue about the first or second chip. Is there anyway to tell anything about them? And is the ATR chip ant good?
