OP welcome to the forums!
I use to have a 08' 328i and it was fun to drive. Mod wise its not going to be a whole lot, but what I've done to it made it more than enough. Had a Active Autowerke tune (stage 2 is available), charcoal delete with drop-in filter, front air scoops, and a BMW Performance exhaust setup. There isn't a purchasable supercharge kit yet on the market. One is still being tested and that can be a while before it comes out. Enjoy your new car, definitely enjoyed mines
