Forgive me for my ignorance but what year did they change the heads and how much performance difference is it. Oh yeah Pcm is the computer right? lol I am trying to keep up with the lingo
yea your on the right track. try to get an 01-02 if possible but a 99-00 will work fine. def. stay away from the 98's. i've worked on a few and have buddies with them, and they all hate them. the only big difference on the 01+ i it comes without an EGR & with an LS6 intake, the computer has a little better operating system also. that can be changed if your tuner knows how (except on a 98')
