PCM is the Performance Control Module, aka your truck's computer. It's located in the engine bay on the passenger side, has three plugs on it. SCT is tuning software that you can use to retune your pcm. There are two ways to go with SCT, the basic XCalibrator which with tunes to load into your pcm, and the PRP (Pro Racer package), which includes the software to do the tuning yourself. Get in touch with Sean Powell, hemifever@aol.com for SCT info. :biggthumpup:
