Anything out there can make my s550 goes little faster.

You could try getting a chip to improve throttle response, but you're not going to be able to gain any 'feelable' power unless you go forced induction.
Chips (if they are out there yet) can help add about 5% hp. Better breathing air filters and an exhaust will do the same, at a relatively low cost.
