Welcome to another Fort Worth guy! Benbrook isn;t that far from most of us--I drive through there once a week or so--I have a couple builders who live off 1187 in Whiskey Flats... Naw man, not need for key cycles or VIn stuff with tuning on our trucks... Having the PCM tuned is quite an easy process--but to eliminate the hassle of having to do security relearns and messing with VATS, you can either have a live tune done by a tuner or you can ship your trucks PCM to a tuner and have him send it back--that way you retain your truck's original PCM with all of the stored codes and stuff. If you want to not void you warranty, GM will install and warranty a S/C on your truck. And as for a cam, you don't wanna go too crazy with FI--they don't like wide LSA's...
