APR Stage 1 horsepower gains
APR’s Stage 1 pump-gas figures are shown below. Choose the row for your fuel grade and exact engine version.
| Calibration / version | Required fuel (U.S. octane) | APR total output | APR maximum horsepower gain |
|---|---|---|---|
| Stage 1 (Sport/Sport+) | 91 AKI | 520 HP | +67 HP |
| Stage 1 (Sport/Sport+) | 93 AKI | 554 HP | +94 HP |
APR describes the gains for this tune as wheel-horsepower gains. Total output and maximum gain are separate figures; maximum gain is not the difference between the two peak horsepower ratings.
These results require Sport or Sport Plus mode. APR’s Normal-mode calibration has different output.
Results vary with fuel quality, vehicle condition, hardware and test conditions. Use the fuel required by the installed APR calibration; verify the exact ECU application before installation.
