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 STAGE 1
The APR Stage 1 ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware modifications and produces up to 559-583 HP with 411-431 FT-LBS of torqueI. Expect +36-59 HP and +24-53 FT-LBS of torque. To get more power, the vehicle can be outfitted with an upgraded intake, catback exhaust, and various other bolt-on modifications all without requiring any new modifications to the ECU.
APR Stage 1 is available for 91 AKI and 93 AKI in North America and 95 RON and 98 RON in the Rest of the World.
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.
