Question about 2007 Chevrolet Colorado (Extended Cab) New Cars
I perchased a surge performance chip to wire in to the IAT sensor, can you tell me if Iwaisted my money?
Those chips are not chips just a 5 cent resistor to alter the IAT (Intake Air Temperature) signal to the PCM (Powertrain Control Module), the idea is that the engine control computer thinks it is getting colder air than it really is and slightly increases spark advance, u will feel no difference in power but u may gain 1 MPG in fuel economy, so u decide. One last note they are illegal in most states that do emission tests, it alters the factory controls.
