    APR ECU Upgrade Stages

    APR’s ECU Upgrades are available in multiple octanes levels. Each stage is fully compatible with an upgraded intake, catback exhaust, or other minor bolt on modifications.

    APR Plus

    The APR Plus ECU Upgrade is the first step towards making more power, and it includes our limited powertrain warranty. This simple upgrade requires no engine hardware modifications, and produces 634 HP with 420 FT-LBS of torque.


    The APR Plus ECU Upgrade matches the performance of our Stage 1 ECU Upgrade (91 octane). To get even more power, you can add any of our other Stage 1 compatible products and still be covered under the APR Plus warranty! If you're not interested in the APR Plus limited powertrain warranty, and want even more power, check out our other Stages.

    APR Stage 1

    The APR Stage I ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware modifications, and produces 634-653 HP with 420-427 FT-LBS of torque depending on fuel grade. Gains as high as 86-104 HP and 53-64 FT-LBS of torque (540 HP Model), 47-66 HP and 29-40 FT-LBS of torque (580 HP Model), and 17-35 HP and 13-30 FT-LBS of torque (610 HP Model) are available throughout the power band, depending on fuel grade and factory output, making the vehicle exceptionally quicker in all scenarios.


    APR Stage 1 is available for 91 AKI, 93 AKI, 100 AKI, 104 AKI, and E60-E85 fuel grades in North America, and 95 RON, 98 RON, 104 RON, 108 RON, and E60-E85 in the Rest of the World.


    Please note, our E85 software is not a full flex fuel program. In this mode the engine is only designed to work on E85, as found directly at the pump, including both summer and winter blends from E60-E85. Using traditional pump fuels in this mode may result in engine damage. Do not manually blend with traditional pump fuel or race fuels or use race specific barrels of E85. To ensure proper E85 content levels, APR recommends using an E85 content sensor. Before using Ethanol, educate yourself and follow our switching guide.
