Hello,

I just bought a 2006 350Z roadster with 32K miles and I was considering a PCD performance chip . Supposedly this will add 55HP and give me better gas mileage for only $69. It looks like you need to cut wires and I am concerned about passing smog in the future and voiding my extended factory warranty. Is this too good to be true? Has anybody added a chip? Another questioin: Will a K&N air filter cause problems with the computer due to the oil coating? Has anybody added a K&N?

THANKS
