I found this auction funny, so i posted it here. I woudnt buy anything like this for $10. Its a good warning for many guys in here who does buy stuff on e-bay like i do. By far not everything there is legit and good to go.
But the $10 for performance chip killed me.
By the way, at first i thought he was selling some sort of plug-n-play software chip, Like "Shark Injection Chip".
