Dyno Testing & Tuning

Our chassis and engine dynos were custom built to provide valid and reliable test results so our technicians can tune your vehicle with pinpoint accuracy.

Timing

We adjust the cam timing to improve low-end torque for a smooth power curve right to the red line. Ignition timing is adjusted to deliver optimal combustion timing for maximum power and fuel efficiency.

Electronic Control Unit

By connecting to your vehicle’s electronic control unit, we can monitor your engine’s response to repeated passes on the dyno. With each pass, we fine-tune your engine until it has a smooth torque curve for a more responsive ride, smoother acceleration and increased power.

Carburetor

We adjust ignition timing and AFR with carb gauges, timing lights, and jetting kits, a necessity after installing any performance parts related to the vehicle’s aspiration system.

Air-Fuel Ratio

Adjusting the AFR of your engine ensures the correct amount of air and fuel are used for complete combustion. AFR is critical to providing power, fuel efficiency, and extending the life of your engine.

Turbo/Supercharger

Superchargers and turbochargers improve performance by delivering more air to the engine, but with increased airflow, the amount of fuel injected into the combustion chambers must be adjusted.

MAT, MAP & EGT

While tuning the engine on the dyno, we measure the changes to Manifold Air Temperature, Manifold Air Pressure, and Exhaust Gas Temperature to determine if the engine’s combustion chambers are receiving the correct mixture of air and fuel, and that ignition is occurring with optimal timing.
“Marc and the staff were awesome to deal with. They got my car dialed-in and made a boat load of torque and hp. Highly recommend this shop!”

dyno testing & tuning services

Chassis dyno tuning

Our chassis dynamometer was custom-built with the best components available. It’s designed to consistently produce valid and reliable results so our expert technicians can custom tune your vehicle with pinpoint accuracy.

engine dyno tuning

Restoring or building an engine for your project can cost thousands of dollars. Dyno testing and tuning your engine before installation ensures that it will run and perform to perfection the first time you turn the key!

custom tunes

We offer our own dyno built tunes on Aliengate or SCT programmers. We can provide a tune for your specific need, whether for towing, racing, improved mileage or for your daily driver. Easy to order and install (free shipping).

fleet tuning

Fleet vehicles tend to operate within defined geographical limits. When an engine is properly tuned to the road conditions and driving style you’ll have fewer repair costs and realize a minimum 10% improvement in fuel efficiency!
