Factory Tune

I recently purchased a used 2015 FoST with some modifications: mainly, an intercooler and catless downpipe. I want to put a tune on the car and I'm unsure if the car currently has a tune already on it (I bought the car from a commercial dealership as a trade-in, and they were completely clueless on any modifications on the car). Can I just by a Cobb Accessport and put a tune on the car without knowing if there is already a tune on the car? Or, do I need to know that the car has a factory tune to put a aftermarket tune on it? Hope that makes sense.
