I don't even need to look to tell you that it is absolutely worthless. If horsepower was that cheap, we would all have fast cars. The only "chipping" you can effectively do to a Maxima is getting a better ECU. Plus, anything that offers $1. for 1HP is bullsh!t.

they are bs, the only thing it does is keeps ur ecu in a open loop wasting more gas.
