With the help of Ethanol, this goal could be done with just a Stage 2+ tune from a reputable brand! Let’s dive into the steps and product recommendations to achieve this impressive performance:

How to Build a 10-Second Audi B9 S4

1. Tuning and ECU Upgrades

• Start with a high-quality ECU tune. Consider options like the 034Motorsport Dynamic+ Tuning or IE's Performance Tune for the EA839 3.0T engine. This will optimize power delivery and drivability. Both companies currently offer up to Stage 3 tunes for when you go big turbo! 
• 034 Dynamic+ ECU & TCU Tune Bundle for B9 Audi S4/S5/SQ5 3.0T
• IE 3.0T Performance Tune - B9 / B9.5 Audi S4 | S5 | SQ5

2. Intake and Downpipe

• For anything above a Stage 2 tune, you will need to upgrade your intake and exhaust. Luckily Brox Tuning has many options.
• B9 S4/S5 Intakes
• B9 S4/S5 Downpipes

3. Intercooler and Cooling

• A better intercooler is essential for consistent performance. This will be a required mod for Stage 2.
• We recommend the CTS Turbo Intercooler for it's performance and attractive price point. 
• Ensure proper cooling with quality coolant and oil.

4. Transmission Upgrades

• Opt for a TCU tune to enhance shifting speed and performance.
• Consider upgrading the transmission mount and inserts for better stability.

5. Suspension and Weight Reduction

• Lowering springs (like the 034Motorsport Dynamic+ Springs) improve handling.
• Reduce weight by removing unnecessary items (e.g., rear seats, spare tire).

6. Tires and Wheels

• Invest in high-performance tires. Hoosier DR2 Radials are a popular choice.
• Lightweight wheels (e.g., Enkei RPF1s) improve acceleration.

7. Safety and Maintenance

• Regular maintenance is crucial. Keep fluids fresh and check for leaks.
• Safety first: Invest in a roll cage if you plan to track your car.

With these modifications, you will be able to run a high 10-second 1/4 mile with the help of E85. If you are limited to pump has (93 octane), you will need a bigger turbo to get into the 10's. We recommend a TTE 710/810 or a Pure 750 Turbo.

Remember, achieving a 10-second quarter-mile time requires a holistic approach. Consult with experts, track your progress, and enjoy the exhilarating ride!
