Review on Optimize Your Vehicle's Performance with Chip Your Car Stage 3 Performance Chip - Boost Up to 60 HP and Gain 5 MPG by Ray Mcknight

This chipmaker claims to increase power, torque and fuel efficiency. I ordered a Premium Stage III chip from the company and installed it according to the instructions. Not only did I not notice any increase in power or torque, but I also noticed reduced fuel efficiency. I contacted the company for a refund and they offered to exchange the chip for the same type. I would not ask for a refund. Unfortunately, the chip really is a scam.
