APR ECU Stage 1 Software Tune - Audi B9 S4/S5 3.0T
The APR Stage I ECU Upgrade is the first step towards making more power! This simple upgrade
requires no engine hardware modifications, and produces 431-480 HP with 467-549 FT-LBS of torque
depending on fuel grade. Gains as high as 85-123 HP and 103-176 FT-LBS of torque are available
throughout the power band, depending on fuel grade and factory output, making the vehicle
exceptionally quicker in all scenarios. APR Stage 1 is available for 91 AKI, 93 AKI, 100 AKI, 104 AKI,
and E60-E85 fuel grades in North America, and 95 RON, 98 RON, 104 RON, 108 RON, and E60-E85
in the Rest of the World.
Please note, our E85 software is not a full flex fuel program. In this mode the engine is only designed
to work on E85, as found directly at the pump, including both summer and winter blends from E60-
E85. Using traditional pump fuels in this mode may result in engine damage. Do not manually blend
with traditional pump fuel or race fuels or use race specific barrels of E85. To ensure proper E85
content levels, APR recommends using an E85 content sensor. Before using Ethanol, educate yourself
and follow our switching guide.
