Simple, your car is no longer OBD-II generic scan capable.

If you got access to 2500 or genesis use the GM key for the OBD generic cable & put it in as a 95 LT1

Just a personal experience with genesis. When i used it, it gave me wrong data. It even ran my ltrims at 50%. The highest is 25%. I tried three different times with genesis when i hooked an auto tap to it i got totally different numbers. It may have just been that shops genesis but i dont think i will trust one agian.

You may have been looking at OEM data stream.
The generic OBD-II is different data stream & specs.
That's what auto tap EFI live & all the others look at.
