You must tell a tuner how you drive the car and if you want more power or more fuel economy. Acura Legend Members Sr5guy and Telion are not responsible for your car's motor damage if the car hasn't been taken to a tuner. If your car breaks, again its not their fault, its the tuners fault. Your local tuner should tell you what your car is capable of doing with the chip installed. Don't go over the Limit!
