So I just married a woman with a gtp 03 and she said she liked it because style and speed cool so now since I have no idea about this car I would like to know a few things .what is the first and easiest power upgrade. I'm used to a 92 5.0 and the easyness of bolt on goodies but now I have a gtp and looking forward to learning about it.what is the stock Hp.what does GTP stand for what r common problems to look out for.can't wait to open this thing up with my wife permition of course hehe thanx
