Hey all. Just wanted to ask a quick question. (sorry if it's been asked before) I just ordered a new 07 QC 1500 4x4 Laramie w/ Hemi engine. What are the capabilities of the factory PCM? What can be changed at the dealership and what has to be changed with aftermarket? Also, does the superchips programmer work on the 07's or is the PCM completely different? Any information would be much appreciated!
