Hey Everyone,
New guy here from Arizona. I just purchased a 2008 Grand Prix GXP. It's factory stock, and I'm just beginning to research where to start modding, so I figured joining the forum would be helpful. I'm new to the LS4 engine, but I used to have an '04 GTP with the L32 some years back I modified moderately. Just figured I'd drop in here and say hi.
