Start with installing a high flow intake and exhaust, once that has been done. Have your PCM re-flashed for a better performance, http://www.pcmforless.com/ is one of the better companies out there that can reprogram your PCM to give you the performance you are looking for.

Feel free to give them a call and they will be more then happy to answer any questions you may have about the programs that they have. Good luck and keep us posted.
