Stage 2 Flex Fuel Tuning Package – Audi RS3 8V2
Unleash the full potential of your 2.5L turbocharged five-cylinder with our Stage 2 Flex Fuel Tuning Package — built for drivers who want big power, daily driveability, and the flexibility to run any ethanol blend from 98 pump gas to full E85. Seamless, smart, and brutally fast.


What’s Included:

🔧 Upgraded Spark Plugs
Colder heat range spark plugs designed for high-boost and ethanol operation. Ensures strong, consistent ignition under extreme cylinder pressures and elevated combustion temperatures.

🌬 High-Flow Air Intake System
Maximizes airflow to the turbocharger while reducing restrictions. Paired with an oiled or dry performance filter and sealed heat shield for optimal turbo response and a more aggressive induction note.

🌀 Turbo Inlet Upgrade
Precision-machined or cast aluminum turbo inlet optimized for higher flow. Reduces pre-turbo restriction, enabling faster spool and higher top-end efficiency — a must for E85 performance.

🔥 High-Flow Downpipe
Stainless steel downpipe with high-flow catalytic converter or decat option. Allows for significantly reduced backpressure, faster turbo spool, and maximum power output at Stage 2 levels.

❄️ Upgraded Intercooler
Larger front-mount intercooler with optimized core and end-tank design. Dramatically reduces intake air temperatures under load, eliminating heat soak and maintaining consistent performance.

🧪 Upgraded Port Fuel Injectors
High-flow auxiliary port injectors designed to support full E85 at Stage 2 power levels. Offers clean, efficient fueling and precise atomization — essential for reliable flex fuel tuning.

📊 Ethanol Content Sensor
Real-time ethanol content monitoring integrated directly into your ECU via the DS1 platform. Automatically adjusts fueling, timing, and boost targets based on fuel blend — no need to reflash for different fuels.

📡 DS1 Tuning Dongle (Dyno Spectrum)
Plug-and-play wireless tuning platform. Flash, datalog, and troubleshoot from your phone or laptop via Wi-Fi. Features real-time map switching, live data viewing, and future expandability (hybrid turbo, etc.).

💻 Custom Stage 2 Flex ECU + TCU Software
Custom-tuned for your specific hardware and driving goals. ECU software dynamically adjusts fueling and timing for any blend of ethanol (E10 to E85). TCU software enhances DSG performance with raised torque limits, faster shift speeds, optimized gear logic, and launch control tuning.


Advanced Software Features:

⚙️ Real-Time Map Switching
Switch between performance maps instantly via cruise control stalk — no need to reflash.

📈 Ethanol % Display in Instrument Cluster
Live ethanol content shown on the digital display — right where you want it.

🚀 Launch Control & Boost-By-Gear Tuning
Fully adjustable launch RPM, boost-by-gear calibration, and torque management for optimal traction and acceleration.


Estimated Performance Gains:

  • Pump Fuel (98 RON): Up to 540–560 Crank HP / 700+ Nm

  • Full E85: Up to 600+ Crank HP / 750+ Nm
    (Power levels vary based on model year, ambient temps, and fuel quality.)


Vehicle Compatibility:

  • Audi RS3 8V (2017–2020) – DAZA/DNWA engine

  • DSG / S-tronic transmission only


Why Go Stage 2 Flex?

This is the ultimate Stage 2 setup for RS3 owners who want supercar-like performance with unmatched flexibility. Run pump gas during the week and switch to E85 for the weekend — no reflash, no compromise, just pure, adaptive power.


One car. Any fuel. All the power.

It fits, but just barely, so it's good that it is sturdy

First and foremost, this part is a fairly poor copy of the OEM part. It's close enough to look good from about 20 feet away, but on close inspection, it has gaps all around. It doesn't follow the curve of the opening properly, and the contours aren't quite right, making it so the outer top corners aren't recessed the way they are supposed to be (see pictures). Some of the tabs don't interface with their mating surfaces because the part is about 5mm too small in the y-axis (see picture). That said, after ordering another similar knock-off, this one is the better of the two. The matte finish is truly matte. The grill slats are thick and beefy, like OEM. The tabs are stout and flexible, not brittle. After much fussing with installation, you should be able to bend your hood tabs (not that you should have to) so all tabs will lock in place. The hardest part for me was getting the outboard-most tab to properly snap in, since the outer top corner of each grill doesn't sit flush inside the recessed relief where it's supposed to sit.

Why pay OEM prices? These kidney grills fit excellent!
