Yep. take out everything you do not need, like the radio, speakers, AC, cruise, power seats etc.
Then consider improving your driving skills with driving schools, driver education track days, and autocross.
Then if you still are burning to spend some money go see Jake at Flat 6 Innovations for some upgrades our rebuilt motor.

I agree with all the above comments.
You have only just purchased the vehicle & you want to up the HP already.
Get some driver training, attend a track day or two. Above all, learn the car & its capabilities (and yours).
I too, thought the "BOX"was sedate, until you hit 4000RPM, then goodbye to most cars. And if the road is twisty, see them at the other end.
Forced induction is going to cost you $$$ and then the engine will have a limited life span.
Good luck with your decision.
