Carbureted & EFI For Increasing Performance

High-Performance EFI Auto Repair in Rockford

The expert mechanics at TJ's Auto Center Inc know switching to fuel injection often improves the fuel efficiency and performance of older carbureted engines. In newer cars, replacing a single fuel injector with a multi-port fuel injector creates an intense, even flow of fuel on each cylinder when your engine needs it most. Feed your engine the fuel it needs with fuel pumps, fuel filters, superchargers, and turbochargers. Break out of gasoline only feed engines by adding a nitrous kit or cooling methanol injection kit.

To ensure the correct air to fuel ratio, TJ's Auto Center Inc can add a new stock-height replacement intake manifold, cold air intake, and fuel rails. Never run rich or lean with a hood scoop, high-performance air filter, and new O2 sensor. Call TJ's Auto Center Inc and talk to us about increasing your car's performance. When you want performance you need the auto repair experts at TJ's Auto Center Inc located at 3427 E State St.

If you're ready to take your car or truck's fuel injection to the next level, TJ's Auto Center Inc is ready with injectors, manifolds, fuel rails, sensors, and complete performance EFI conversion kits. From BMW to Audi to Corvette, TJ's Auto Center Inc has you covered.

Tuning Old School Carburetors For True Muscle

Your muscle car may be starving for air! Bring it to TJ's Auto Center Inc and find out. Because of operating losses in the intake runner and cylinder with newer unleaded fuels that do not fully vaporize in the combustion chamber, cars tuned to the manufacturer's specifications can run lean. TJ's Auto Center Inc can diagnose if you are actually running leaner than the manufacturer suggested ratio of 14.7:1 air to fuel mixture. Bring your classic car to TJ's Auto Center Inc at 3427 E State St to tune the perfect air to fuel mixture and correct ignition spark for maximum power.
