Why Run Flex Fuel Tunes on Your Golf R / S3?
- Power You Can Feel: Ethanol’s higher octane rating allows for increased timing and boost, giving your engine the potential to produce significantly more power.
- Seamless Adaptability: Ethanol blends like E10, E50, or E85 are all fair game, giving you the ultimate flexibility at the pump without sacrificing power and having to switch tunes.
- Cooler Combustion: Ethanol burns cooler than gasoline, which helps reduce engine temperatures and minimizes the risk of knock, especially during high-performance driving.
- Cleaner Burn: Ethanol burns cleaner, leaving less carbon buildup in the engine. This means a healthier engine and better long-term performance.
- Cost-Effective Power Gains: Ethanol-rich fuels like E85 are often more affordable than premium gasoline, letting you enjoy top-tier performance without breaking the bank.
