APR ECU UPGRADE STAGES
Each stage includes several adjustments and features to make the driving experience more enjoyable. We’ve not only made the engine more powerful, but we’ve improved acceleration, removed the speed limiter, enabled left-foot braking or brake boosting, properly rescaled the boost gauge, increased the stationary rev limiter, optimized thermal management and protection, designed the software to support normal bolt on modifications while not requiring any for the baseline configuration, and eliminated the need for a TCU upgrade to deliver maximum torque while still accurately reporting torque to the ECU.
- APR PLUS
- APR STAGE 1
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 479 HP with 533 FT-LBS of torque. Gains as high as 56 HP and 88 FT-LBS of torque are available throughout the power band, making the vehicle exceptionally quicker in all scenarios.
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.

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.
