EFI Conversions
Modern performance starts with modern fuel delivery. If you’re still running a carburetor, upgrading to Electronic Fuel Injection (EFI) is one of the best investments you can make in your engine. At Johnson Performance & Dyno Service, we design, install, and tune EFI systems that bring today’s technology to your classic, street, or race build.
Power Adder Options
- Instant Starting – Fires up in any weather, hot or cold.
- Consistent Performance – Altitude, temperature, and humidity are no longer performance killers.
- More Power, Better Economy – Precision fuel delivery means you get the most horsepower per drop of gas.
- Low Maintenance – No jets, no floats, no constant fiddling. Just reliable performance.
- Cleaner Emissions – Efficient combustion that meets today’s standards.
Professional Installation & Dyno Tuning
An EFI conversion is more than bolting on a kit—it’s about calibration. That’s where our in-house dyno tuning makes the difference. Once your system is installed, we fine-tune fuel and ignition curves to match your engine’s unique needs, whether it’s a mild cruiser or a high-compression race build.
With our dyno, you’ll know exactly what your engine is putting down in horsepower, torque, and efficiency. More importantly, you’ll leave with a setup that’s safe, reliable, and built for the way you drive.
From carb swaps to full custom EFI systems, we’ve got the knowledge and the tools to do it right. EFI brings the best of today’s performance technology to yesterday’s engines—and we make sure it’s dialed in for maximum results.
