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 — B8 | 91 AKI | 256 HP | +55 HP |
| Stage 1 — B8.5 | 91 AKI | 270 HP | +43 HP |
| Stage 1 — B8 | 93 AKI | 266 HP | +66 HP |
| Stage 1 — B8.5 | 93 AKI | 284 HP | +57 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.
Factory versions and chassis are shown separately because their gains differ. A power-table row does not extend the confirmed vehicle fitment below.
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.
