There are install diagrams at the sites where you buy the chips from but if you are new to the scene you may want to get it done by a pro.
For that, send a pm to spedmetal and he can help you with the install. He is extremely good at what he does. He chipped mine and in 2 days i had it back. I payed the extra for overnite shipping but even if you go with the slowest form of snail mail, it will be pretty quick.
As already recommended by Lufcfan, The ultimate info sticky has very good information and will help bring you up to speed here.
Edit: The duo2 chip lufcfan recommended is also a very good choice.
btw, welcome to the forums!
