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 | Peak horsepower increase (calculated) |
|---|---|---|---|
| Stage 1 — Cayenne Turbo, 440 HP baseline | 91 AKI | 487 HP | +47 HP (calculated peak difference) |
| Stage 1 — Cayenne Turbo, 440 HP baseline | 93 AKI | 493 HP | +53 HP (calculated peak difference) |
The increase is calculated from APR’s listed tuned peak horsepower minus its 440 HP stock baseline. It is not an APR-published maximum gain across the RPM range.
These numerical results apply to the 440 HP Cayenne Turbo baseline. APR states the Turbo S can produce more power but does not provide a separate Turbo S gain in this table.
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.
