- Question
Hey, by chance is APR coming up with a stage 2 tune, for the C8 s6 lineup?
By Sohail Zahir on June 16, 2023
AnswerThe S6 does not benefit from further stage tuning on the factory turbos. You a bolt on any standard mod (other than fueling / turbo) without changing the tune.Helpful?
APR ECU Upgrade Stages
Each stage includes several adjustments and features to make the driving experience more enjoyable. We’ve not only made the engine more powerful, but we’ve improved acceleration, removed the speed limiter, enabled left-foot braking or brake boosting, properly rescaled the boost gauge, increased the stationary rev limiter, optimized thermal management and protection, designed the software to support normal bolt on modifications while not requiring any for the baseline configuration, and eliminated the need for a TCU upgrade to deliver maximum torque while still accurately reporting torque to the ECU.
Our ECU Upgrades are available in multiple configurations. Installation of additional performance hardware, such as an intercooler or intake systems, may provide further performance improvements.
APR Stage 1
The APR Stage 1 ECU Upgrade is the first step towards tuning your engine. It produces up to 479-531 HP and 533-605 FT-LBS of torque with gains as high as +56-109 HP and +88-160 FT-LBS of torque at the wheels.
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.
APR Plus
APR Plus is our APR Stage 1 ECU Upgrade with our limited powertrain warranty and it’s the first step towards tuning your engine. It produces up to 479 HP and 533 FT-LBS of torque with gains as high as +56 HP and +88 FT-LBS of torque at the wheels. Please check our warranty manual to understand modifications supported by APR Plus.

Only use fuel equal to or higher than specified. Never use a lower octane fuel. Always follow our fuel guide, especially with race fuel and Ethanol, where available. Dynos are for reference only. Results will vary. Contributing factors include the vehicle condition, vehicle setup, dyno type, dyno setup, environmental factors, fuel quality, and more. When describing fuels, the North American Region (NAR) uses the Anti-Knock Index (AKI), (RON+MON)/2, or (R+M)/2. The Rest of the World (ROW) uses RON. RON is Research Octane Number and MON is Motor Octane Number.
