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 | 644 HP | +107 AWHP |
| Stage 1 | 93 AKI | 663 HP | +134 AWHP |
| Stage 1 | 93 AKI (High TQ TCU Required) | 665 HP | +138 AWHP |
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.
Rows marked “High TQ TCU Required” require the corresponding transmission software.
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.

Fitment requirements
- Non-hybrid Turbo; not Turbo S E-Hybrid. Confirm exact ECU/TCU box code, software revision, fuel grade and required hardware with APR before installation. A vehicle/engine match alone does not confirm software availability.
- Turbo Sport Turismo begins with US model year 2018. Non-hybrid Turbo only; Turbo S E-Hybrid is excluded. PDK tuning is by request and is not included. Kies must confirm a supported stock-TCU/low-torque Stage 1 calibration; high-torque files require separately approved PDK software.

The displayed price is for APR software. Kies installation is an additional $150, with a 45-minute flashing allowance after compatibility and ECU access are confirmed. Tax and any separately required work are additional. Standalone online software checkout is not available.
Compatibility and calibration
Kies must verify the VIN, exact trim, ECU/TCU box codes, software versions, fuel grade and required hardware. This listing excludes Turbo S E-Hybrid, other hybrid models and other Panamera generations or trims. Power gains depend on the approved calibration and vehicle; no horsepower result is guaranteed.
PDK tuning is by request and is not included. Kies must confirm a supported stock-TCU/low-torque Stage 1 calibration. High-torque files require separately approved PDK software, with its own compatibility review, price and appointment allowance.
For supported at-home flashing, the APR Ultralink device is sold separately. Device purchases do not include tuning software, an ECU unlock or Kies installation; APR software is purchased separately through the APR Marketplace.
