Review on Innovative Performance Chip/Power Programmer for Nissan Altima 2.0L, 2.4L, 2.5L, and 3.5L - Enhance Fuel Efficiency, Save Gas, Boost MPG, Amplify Horsepower & Torque! by Micheal Wolf

is terrible. Long story short, I have a '07 Altima 3.5 and was trying to apply this chip. The product comes with "clips" for your wires connected to the main air sensor (MAF) to try to change your settings. giving you "more" horsepower and "better fuel economy". Unfortunately I can't tell you if this is true or not as my wires were completely cut in half by this horrible product. Although Revain will give me a full refund I can't complain too much. how i fixed it: i stripped the wires, twisted them together and then taped them.
