Tuning?

This is something that has been nagging me for a while now. I played the original Forza Horizon and loved it, but I feel the thing that bugged me the most about it all was that there was no tuning, only upgrades. Which basically meant multiplayer was whoever had the most money and horsepower. Will this be included with the same caliber it was in forza 4/5?
