Add power and fuel economy to your compact station wagon with our Chevy HHR powertrain control modules (PCM). A new HHR PCM piggybacks your Engine Control Unit (ECU) to modify the signal and resend it to your car's computer, thereby never altering factory settings. That means you see more horsepower and better gas mileage with the Chevy HHR PCM.
