i just realized something. i really need this, and this would be a great chance to buy it since im not driving my car right now. but i know nothing about ordering this thing. to tell you the truth i dont even know what core charge is
. but anyways do i unplug my PCM, mail it to them and they reprogram it, and then i get it back? and do i give them 100$ along with my PCM (at the same time). i honestly have no idea, please someone correct me if im worng. also where exactly is that PCM located at anyway?
