Your car comes with a factory-tuned engine control unit (ECU). As far as stock ECUs go, however, they only provide so-so performance. If you want to get the most power out of your car, you should go for a performance module.First, here's a look at some basics. Your car's stock ECU is designed to control key engine functions such as mixing air and fuel, timing of ignition, and/or cam profile for engines with variable valve timing systems, and recording mechanical or electrical failures. The main aim of stock ECU programming is a balance between optimum performance and fuel efficiency. What it doesn't give is maximum performance adjustments for racing applications.That's what a performance module is for-tweaking the engine's performance for maximum torque and horsepower delivery at all engine speeds and improving engine response. The module even diagnoses engine faults so you can solve them without paying for professional services. Excited? You should be.Carparts has a large inventory of performance modules for any car make and model.

• Tweaks engine performance for maximum torque and horsepower delivery

• Improves engine response

• Helps your car achieve peak engine efficiency depending on octane rating of fuel

    After installing each performance module, we drove our Corvette to check if its overall performance improved. With the Jet Performance module, we noticed an increase in gas mileage of about 2 to 3 mpg. There was also a considerable boost in our Corvette's top speed. Likewise, with Hypertech, our vehicle gained a small increase in horsepower, and it's temperature ran a little cooler.
