Unfortunately a "plug n play" application for our cars (read Hypertech) will net you about 3 HP and costs around $300. That's pretty expensive HP. If you don't have any other modifications you're not going to get any benefit out of a new tune. The "chips" you see on ebay trick the computer for a few weeks (into running rich) and then the car figures it out, rewrites the fuel trims and you're back to where you started. If you don't have any other modifications I highly recommend reading the "Where to start Modding" sticky at the top of the 4th Gen section.
