What is an engine tuneup?

An engine tuneup is a comprehensive service to maintain or improve engine performance. It includes checking cylinder compression, spark plugs, filters, ignition timing, and fuel delivery. Regular tuneups prevent major engine issues and maintain fuel efficiency.

How do I know if my engine needs tuning?

Symptoms include rough idling, reduced power, poor fuel economy, or difficulty starting. Misfires or unusual exhaust smoke are also signs. Early attention ensures the engine continues to perform reliably.

What is cylinder leakdown testing?

Leakdown testing measures how well each cylinder holds pressure. It helps identify leaks at valves, gaskets or piston rings. This diagnostic tool ensures precise tuning and helps prevent future engine damage.

Do you tune performance or modified engines?

Yes, we work on performance vehicles, hot rods, custom engines, turbocharged and supercharged motors. We also tune naturally aspirated engines, including carbureted and EFI systems. Our experience ensures high-performance results.

What is included in a fuel system tune?

Fuel system tune includes carburetor adjustment, fuel pump inspection, and air-fuel ratio tuning. Proper fuel delivery is essential for combustion efficiency. We also check emissions profiles for optimal performance.

Do you adjust ignition timing?

Yes, we check and adjust ignition timing to ensure efficient combustion. Correct timing improves power, fuel economy, and reduces engine knock. Timing adjustments are essential for both naturally aspirated and forced induction engines.

How often should I get an engine tuneup?

Generally every 15,000 to 30,000 km depending on the vehicle and driving conditions. High-performance or modified vehicles may require more frequent attention. Regular tuneups help maintain performance and reliability.

Do you replace spark plugs and filters during a tuneup?

Yes, spark plugs, air filters, and oil filters are checked and replaced as necessary. Clean filters and properly gapped plugs are critical for engine efficiency and longevity.

Can engine tuning improve fuel economy?

Yes, precise tuning restores optimal combustion, reducing fuel waste. This results in smoother performance, better throttle response, and improved fuel economy.

Do you work on electronic engine management systems?

Absolutely, we check engine management systems, ignition coils, crank angle sensors, and EFI components. This ensures modern vehicles receive accurate tuning and diagnostics.

Leakdown Testing and Compression Checks

Leakdown testing measures cylinder sealing integrity, helping us pinpoint worn valves, gaskets, or piston rings. Accurate compression readings are critical to identify hidden engine issues. Early detection prevents costly repairs and ensures the engine runs efficiently.

Fuel Delivery and Carburetor Servicing

We service, tune, and repair carburetors and fuel pumps where applicable, ensuring optimal air-fuel mixture. For EFI engines, fuel injectors are cleaned and tested for proper spray patterns. This guarantees efficient combustion and reduces emissions.

Ignition and Timing Adjustments

Ignition timing and engine timing are critical to engine performance. We test and adjust all ignition components, including coils, HT leads, and sensors, to ensure maximum power delivery and smooth running. Proper timing prevents knock and uneven performance.

Filters and Routine Replacements

We check and replace spark plugs, air filters, and oil filters as needed. Clean components maintain airflow and combustion efficiency. This is essential for both daily drivers and high-performance vehicles.
