I'm new to this site and I already can use help. I recently bought a stock 99 'gt/auto. I have a friend who recently bought a stock 04' GTO/auto with the LS1. What mods do I need to edge the GTO? Its only a matter of time before we meet, and when that time comes, I want to be more than ready. I've never backed down from a race, and I won't now. I know it's heavier than the stang, but I also know that it puts out more hp. I'm going to start modding next month, and I would appreciate anyones help.thanx'
