I think I might be in the market for a new tuner. This spring I think I am going to tear into the 04 and clean it up. Nothing crazy being that it is a legit black 40th GT. I have been using the Sniper Special Forces tuning software for years and have loved it but, being that it is windows XP based and, Microsoft doesn't offer support for XP any more, I am worried that it could come back to bite me in the a$$ one day. I am doing some research on my own but, would like to hear some of your opinions. I might stay with some new Sniper stuff as I have had awesome luck with their customer service.
