If I am not mistaken though, it still has your stock tune in it which means it is locked to your car. Not trying to be argumentative but I am interested and want to understand this. Once you use a tuner, it is locked to your car with the stock tune. Unless you have had SCT unlock it, it will be locked. Again, I am not sure and maybe someone that knows for sure can chime in here.
I don't understand how it can have five open spots when you say you have three tunes. Maybe the newer SCT's have more options.
Sorry if I am asking a lot of questions but just trying to understand. Thanks
