How do you add a performance chip to a Nissan 300zx?

im pretty sure you would put the new chip in the ECU which is most likely located underneath the wooden pad and carpet underneath the glove box on the passenger side.


- also, you will need to take your vehicle to some sort of a performance shop because the chip will need to be saughtered where the stock chip was located. be careful when taking the screws off the actual computer inside the gold box. the computer is very sensitive and parts are easily knocked off. I'd say the the whole thing wont take any longer then an hour, and about $60 for the saughtering.
