APR is well-known for their substantial performance upgrades with the thought of your vehicle’s reliability in mind. To them, it's all about enhancing the driving experience. If it doesn't make your vehicle perform better, stop quicker, turn flatter, and more fun, they don't have it.  You can check out available products here: www.goapr.com/products


APR's software replaces the standard software in your car's Engine Control Module (ECM or ECU) increasing horsepower and torque. It’s programmed to adjust ignition timing, fuel delivery, fuel metering, boost settings, rev limiters, and/or speed limiters to optimize performance and, in some applications, fuel economy. This is done by Direct Port Programming through the ODB-II port.

APR offers a total of five different programs, but not all ECU's can hold multiple programs. The programs currently offered:

  • Stock mode

  • 91 Octane mode

  • 93 Octane mode

  • 100 Octane mode

  • Valet mode

These programs are available at the touch of a button. APR has taken your cruise control buttons and utilized them for this function. Your cruise control will continue to function as normal, but will give you the ability to scroll through the programs you have purchased on your APR tuned ECU.


APR's software upgrades take advantage of their aftermarket parts, such as, turbocharger systems, exhaust upgrades, fuel system upgrades, and more.
