hmmm so i send PFYC.com 100$ and they send me a PCM and just take mine out and throw it away or what? the PCM in mine is pretty good, it takes good care of my engine and lets it run really strong. i dont really understand how they do this
do they take a PCM fro ma stock alero and reprogram it to a certain level?? or do they get a brand new one from GM? because what i think my PCM is adapted to a harder working engine, but i dont understand what will happen if they give me a PCM thats from some stock alero that hasnt adapted to its engine like mine, wont this make anything wierd? oh yeah and is it true i have to run better than 87 octane gas for this thing to work? and what happens if i use 87 octane? will it f*** up?
