Why You Should Be Running E85
E85 isn’t just for race cars. It’s a powerhouse fuel that’s widely available and seriously underrated. Here’s why you should be running it in your GM truck or SUV:
- More Power: E85 has an octane rating of 100-105, allowing for more aggressive timing and higher compression—aka more horsepower.
- Cheaper Fuel: E85 is usually way cheaper than premium gas, meaning you save at the pump while making more power.
- Lower Engine Temps: Ethanol burns cooler than gasoline, reducing wear and extending engine life.
- Cleaner Emissions: Less carbon buildup, fewer greenhouse gases, and a happier planet.
- Detonation Resistance: The high octane rating helps prevent knock, making your engine run safer and stronger.
- Renewable & Sustainable: Made from corn and other biofuels, reducing dependence on fossil fuels.
Advanced Fuel Dynamics: Born from Frustration, Built for Performance
Back in 2014, a tuner got fed up with E85 tunes that never seemed quite right. The problem? Pump E85 is all over the place when it comes to ethanol content, and a fixed tune can’t compensate for that. The solution? A real flex fuel system that constantly adjusts in real-time—thus, Advanced Fuel Dynamics was born. Since then, they’ve been cranking out battle-tested fuel solutions for street, strip, and dyno warriors alike.
