You don't need to buy a car or be in one to "tune" your fist. You just need a place with some privacy (preferably).

Pull out and buy a 430/500/55/63 (depending on your budget) instead?
In all seriousness, you are not going to make any meaningful power increases to that car unless you are prepared to spend some serious money, hence you may as well enjoy it for what it is and upgrade to a better model when funds allow.
