When you do a lot of work, as Juan Navedo has on this hot vintage 55 Chevy, it tends to turn a lot of heads on the street and on the show circuit. This is not Juan’s first time down the custom road. As an electronics technician by trade and an automotive hobbyist by choice, he has owned 15 customized vehicles over the years, and his 55 Chevy pickup is the culmination of all those years of experience. It ranks at the top of his list.

Super-High Super Duty
Tall lift kits used to mean a rough ride. Times have changed—the suspension aftermarket has figured out how to accommodate huge meats without inflicting permanent kidney damage on the driver and passengers. Computer-modeling and other engineering advancements prioritize ride quality into the suspension design.

LS Fest is our kind of playground—a realm where automotive dreams become reality, and where the heart of every beastly machine, the LS and current gen LT engines reign supreme. It’s more than just an event; it’s a symphony of speed and power, where passion and performance converge in a thunderous cacophony of horsepower. And at the heart of it all lies E85, the elixir that propels these mechanical marvels to dizzying heights.
Pure Adrenaline for Your Engine
Now, why E85, you might wonder? It’s simple, really. With its potent blend of up to 85% ethanol, E85 is the undisputed choice fuel of speed freaks seeking peak performance. Its sky-high octane rating and unmatched cooling prowess make it the go-to fuel for those craving maximum performance. The denser intake charge it provides translates into jaw-dropping gains in horsepower and torque, igniting the adrenaline of every racer on the track.
But E85 isn’t just about brute power; it’s about practicality too. Unlike pure alcohol fuels, it’s less corrosive and easier to ignite, making it a user-friendly powerhouse. Its exceptional knock resistance allows engines to run at higher compression ratios, squeezing every drop of power from the roaring beasts under the hood.
And let’s talk forced induction engines—they absolutely thrive on E85. Its ability to handle higher boost levels than traditional gasoline can double the output, transforming already formidable machines into rockets on wheels. In essence, E85 is the cost-effective, high-octane rocket fuel that LS Fest racers rely on to unlock their machines’ ultimate potential.
While at LS Fest, we noticed several drivers spending a lot of time tuning their rides before hitting the track, dialing them in to try and gain an edge over the competition. This left us puzzled. If you’re looking for an edge, there’s no better way to optimize your performance with E85 than with a flex fuel system from Advanced Fuel Dynamics.
Flexing like a Pro
Now, when it comes to maximizing performance, look no further than Advanced Fuel Dynamics (AFD). Their ProFlex Commander is a game-changer in the world of performance flex fuel systems. Unlike other systems out there, it doesn’t tie you down to just one fuel blend. No sir, it’s like having your own personal tuner riding shotgun, making adjustments on the fly to whatever mix of ethanol you’ve got in your tank.
AFD places safety at the forefront of their design philosophy. These systems undergo rigorous dyno-testing to guarantee they deliver performance enhancements while steadfastly maintaining engine safety.
Installation is easy. Just plug it in and you’re good to go. In under an hour you’ll be ready to hit the road while the guys using other E85 systems are on their laptops, dialing in their rides. With the ProFlex Commander, its instant automatic adjustments ensure your engine runs smoothly, regardless of ethanol content. Just plug it in and forget it. No more juggling multiple maps or manual tweaks—the ProFlex Commander handles it all, effortlessly optimizing your performance.
Don’t just take our word for it. At the 2024 Holley LS Fest Texas, Mike Phillips clinched several victories and came tantalizingly close to breaking into the Top 4 at the Drifting Competition. Battling it out in his C6 Corvette—a “street car” no less—against a lineup of fully-built competition machines, Phillips showcased exceptional skill and determination, and attributes much of his success to the Advanced Fuel Dynamics flex fuel system, which significantly boosted his car’s power just in time for the showdown.
So if you’re looking for quick and easy horsepower gains for a competitive edge on the track or just want to maximize the benefits E85 in your daily commute, look no further than Advanced Fuel Dynamics. Head on over to the Advanced Fuel Dynamics website to learn more.
