Im about to buy a pcm for my 98 gtp and have following mods already , K&n drop in, autolite iridium plugs, tranny cooler, and a resonator delete. Will the pcm help or hurt my car. Is it overall safe enough for my car? Im not the kind that likes top end I just like acceleration every once in a while. I plan on doing a few more small mods later such a more exhaust work. What will the pcm do for my car positively speaking. Any better acceleration? Also would it be good to go ahead and install.
