05GT Guru Posted January 5, 2009 Share Posted January 5, 2009 Protune is the best way to go. Its safer and makes more power. Its a win win in every sense of the term if you have a tuner who knows what hes doing. Even though all lgts use the same parts they arent the same when it comes to tuning. A generic tune just doesnt cut it in my book Link to comment Share on other sites More sharing options...
