No performance chips that I know of. Our ECU isn't exactly easy to hack into. No one wants to play around with it. The ECU is constantly changing the fuel map and timing due to our VVTI system, and the way we position our throttle.

Ebay stuff is nothing but a resistor that you can get from radio shack for like >$1.00. Not even worth getting into what exactly does..
waste of money....

only thing that comes close to a chip is gettin the srt intake with piggy back ecu. i notice a good midrange performance with mine being thought i have a gs300 but it seems like i lost a little low end. So i removed mine and got my low end back. Thats just my personal experience with it. I rally dont know of any other route to go unless u go FI (forced induction- turbo, or supercharger).
