Ultrasonic fuel injector cleaning and flow testing is the only fuel injector cleaning method that guarantees reliable and measurable results. No other injection cleaning method can claim such results. The goal of fuel injector cleaning is to remove hydrocarbons and deposits from the internal components of the fuel injector.

Car diagnostic tests scan your car's components and systems to check for issues with components like the engine, transmission, oil tank, throttle, and many more.

Upgrading to an increased ride height suspension can allow for longer suspension travel and unhindered wheel articulation, as well as giving more body clearance to obstacles and allowing the fitment of larger off road biased tires.

Lethal Performance has the capability to engineer and develop custom fabricated parts and mounts.

We can make whatever you need.

Have a dream? Let us help you make it a reality. We do complete builds for anything you can imagine.

Dyno tuning is the only precise way of dialing in your engine and configuring temperature, manifold pressure, air/fuel ratios, torque and horsepower for optimal results.

You may want to consider reflashing after installing performance parts. A professional tune is highly recommended when used in conjunction with other performance parts.

A supercharger is an air compressor that increases the pressure or density of air supplied to an internal combustion engine. This gives each intake cycle of the engine more oxygen, letting it burn more fuel and do more work, thus increasing the power output.

If you're looking for substantial gains in your car's performance, you might want to consider a turbo kit. A turbocharger is essentially an exhaust driven air compressor. A turbo kit can generate power by forcing air into the engine at a much higher pressure, increasing power potential.
