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 | 240 HP | +42 HP |
| Stage 1 | 93 AKI | 251 HP | +50 HP |
Output and gains retain APR’s published units. WHP/AWHP denotes horsepower at the wheels. Maximum gain is a separate figure and need not equal the difference between 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.
