Only use fuel equal to or higher than specified. Never use a lower octane fuel. Always follow our fuel guide, especially with race fuel and Ethanol, where available. Dynos are for reference only. Results will vary. Contributing factors include the vehicle condition, vehicle setup, dyno type, dyno setup, environmental factors, fuel quality, and more. When describing fuels, the North American Region (NAR) uses the Anti-Knock Index (AKI), (RON+MON)/2, or (R+M)/2. The Rest of the World (ROW) uses RON. RON is Research Octane Number and MON is Motor Octane Number.

    When you buy an APR Ultralink you use it to buy and install APR software on your vehicle, from the convenience of your own home, from the Ultralink Marketplace. Alternatively, you can always go to an APR dealer and they will sell and install software for you. Below is the retail price for most of our software. Any sales or promotions will not be reflected in these prices but will be in the Ultralink Marketplace. Learn more about the Ultralink here.

    Our new suite of MG1 ECU software comes after months of extensive research and development that is typically absent from the aftermarket. Our upgrade makes the engine more powerful and more exciting. We’ve extensively calibrated the system to work flawlessly on the track, while retaining safety routines to protect your engine in the most demanding scenarios. This was all made possible by our engineering team's pursuit of perfection. Development vehicles were outfitted with additional sensors, including turbo shaft speed sensors, thermocouples, transducers, and more, along with our high speed direct RAM logging equipment, to feed valuable data to the team for analysis. After thousands of hours of testing and tuning we created new calibrations that are fine tuned for several octanes and contain hundreds of map changes, with a vast array of safety features built in.


    The result of this work is nothing short of astounding. Not only have we increase power, we’ve added many safety routines to ensure the engine and components are protected under demanding scenarios. Additionally we’ve added features to enhance the driving experience.


    We’ve recalibrated the exhaust flaps to reduce backpressure and create consistent turbo spool characteristics. Sound characteristics are improved too, especially during free-rev, which sees its limiter raise in park and neutral. We’ve retained factory exhaust crackle, which mimics much of the behavior of the RS models without being over-the-top and obnoxious. This enables during free-rev, downshifts, and lifting off the throttle. It’s optimized with exhaust flap actuation, and includes safety routines to ensure component protection. Through proper torque management and ECU code changes, we’ve removed the requirement of a transmission tune to achieve full torque. We’ve optimized launch control for a better take-off and enabled boost building on the line. Additionally we’ve defaulted the start-stop feature to the off position, removed the speed limiter, added left-foot braking or brake-boosting, and configured the ECU to send the correct calibration to the dash for the performance gauges.


    To protect the engine and components we’ve spent a considerable amount of time tuning safety routines, some of which were not active from the factory. The ECU will protect the engine should the exhaust flaps fail as back pressure becomes too high. The optional exhaust crackle feature will turn off should components get too hot. The engine has advanced LSPI protection to prevent the engine from damage when being lugged in the tallest gears. Excessive intake air temperature, which is common on a dynamometer, will cause power to reduce to protect the engine. Furthermore more we’ve added and calibrated protection routines for turbocharger pressure ratios, shaft speed, exhaust pressure, intake air temperature, coolant temperature, oil temperature, lambda, fueling system limitations, and more. All of this and more gives us confidence to offer an optional limited powertrain warranty through APR Plus!


    Our ECU Upgrades are available in multiple configurations. Installation of additional performance hardware, such as an intercooler or intake systems, may provide further performance improvements.

    APR Stage 1

    The APR Stage 1 ECU Upgrade is the first step towards tuning your engine. It produces up to 411-491 HP and 551-629 FT-LBS of torque with gains as high as +103-171 HP and +190-249 FT-LBS of torque at the wheels.


    This tune is available for 91, 93, 100, and 104 AKI fuel grades, as well as E60-E85 Ethanol in North America and 91, 95, 98, 104, and 108 RON fuel grades, and E60-E85 Ethanol in the ROW.

    APR Plus

    APR Plus is our APR Stage 1 ECU Upgrade with our limited powertrain warranty and it’s the first step towards tuning your engine. It produces up to 411 HP and 551 FT-LBS of torque with gains as high as +103 HP and +190 FT-LBS of torque at the wheels. Please check our warranty manual to understand modifications supported by APR Plus.

    APR Stage 3 (DTR8868) Turbo Upgrade Software

    The APR Stage 3 ECU Upgrade is the next step towards tuning your engine. It produces up to 529-620 HP and 554-622 FT-LBS of torque with gains as high as +172-171 HP and +255-263 FT-LBS of torque at the wheels. Use this tune with the APR DTR8868 turbocharger.


    This tune is available for 91, 93, 100, and 104 AKI fuel grades, as well as E60-E85 Ethanol in North America and 91, 95, 98, 104, and 108 RON fuel grades, and E60-E85 Ethanol in the ROW. When selecting a fuel grade, a minimum of that fuel grade must be used. Using higher fuel grades is permissible.
