I have a 97 gtp whose pcm has the KR built in. Once upon a time it was hopped up, then, sadlly, I took it into GM but forgot to tell them not to reflash it. Thus it is back to stock (what a difference).

The 98 -03 models do not have that anti KR thing.

I have a DHP as well as an Overkill PCM which I believe came off of 98 models that I've acquired over the years.

Has anyone tried to use a hopped up PCM in a 97 model and/or will it work?

Thanks
