I will tell if it makes a good difference or not I'm hopefully flashing on a stock car this weekend so we'll see. Maybe it'll pop a disa valve shadow code or who knows.

Update: You will definitely gain power on a fully stock car. I will dare to say the tune itself is about half the power of the whole swap then the other is the manifold with the variable runners itself. Every 328 even if meant to stay stock should get flashed with the 330i tune.
