Electronic Performance

---

Electronic performance modifications are by far the most common performance part we sell, and one of the easiest to install. These products create the most noticeable difference in power gains and are classified by two general types of units:

The "Performance Module" installs under the hood and works by altering your vehicle's stock ECU parameters. The main benefit with most of these units is on-the-fly adjustability (changing power levels while you drive) with a switch, or on more advanced units a display that provides additional monitoring and safety features.

The "Downloader/Programmer" works by downloading and storing your stock computer's information, then uploading a new program to the vehicle's ECU. Benefits of these units include no physical parts actually being installed on the vehicle and the overall ease of use.
