We don't have "chips." You have a PCM. There are many threads about increasing horsepower here. Installing a K & N CAI isn't necessarily going to gain much if any. Get your wallet out and start at the back, Catback, gears, correct headers, PCM tune. Spend some time reading the threads. Before you start, make sure everything is in good condition stock. Plugs, wires, properly functioning Opti vent harness, wiring and grounds good. Good luck.
