Well then it sounds like i have nothing to worry about with the pcm.. the original owner said he never scanned for kr but I have all the supporting mods for the smaller pulley.. so should i really be worried about it?
Just get a scanner and keep an eye on everything.. If you have the supporting mods you still need to scan to make sure your going to lose the front bank of pistons.... On a side note, I would consider headers before you drop down to a 3.4...
