I just bought an '08 G37S and a friend mentioned getting a performance chip. Can anyone tell me what they are and how much HP they can give? How much do they cost? Is it a good to get eventually? Thanks!

 

Racing chips arent going to give u much more horsepower anywhere from 15-30 horses. As far as cost goes it ranges. You could try searching these forums 1st to find your answer. Maybe even google idk i must be crazy.

 

If you search the forums they are all over the place. Uprev, bullydog, hypertech.
