About this product
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.
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.
Low- and high-torque files are different calibrations. Select the file appropriate for the vehicle’s transmission, clutch and any required TCU software.
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.
