Is there a PCM difference in vettes? 97-99
2) Define desireable- this is a subjective question. Without further definition, it is meaningless. If your desires are to use the Pcm soley in some sort of forced induction the newer Pcm's are capable of running different Operating Systems that have more features. This is not to say that you can't run a stout forced induction system with the earlier Pcm's. There are many on this board who have very awesome vehicles that are running 97-98 OS'/Pcms' with many approaches to doing it. HP Tuners offers a 2bar setup for 98s...there are other methods, search. There are many ways to skin a kat.
