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 | 91 AKI | 393 HP | +95 HP |
| Stage 1 | 93 AKI | 407 HP | +111 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.
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.
