Services • Engine Tuning
Engine tuning for smooth power, clean idle, and reliable starts
From drivability issues to performance optimization, our ASE-certified technicians tune Japanese vehicles with factory-level diagnostics, OEM-quality parts, and transparent recommendations.
What we do
What’s included in an engine tune-up
We tailor the service to your vehicle’s mileage, symptoms, and maintenance history—no one-size-fits-all packages.
Computer diagnostics & data review
Scan for codes, review live data, and verify fuel trims, misfire counters, and sensor performance to pinpoint the cause—not just the symptom.
Ignition system inspection
Check spark plugs, coils, and related components for wear, heat damage, or incorrect gaps, and replace as needed with OEM-spec parts.
Air & fuel delivery checks
Inspect intake leaks, throttle body condition, MAF/MAP readings, and fuel pressure where applicable to restore proper air/fuel balance.
Road test & verification
Confirm smooth idle, crisp throttle response, and stable fuel trims after service, then document results for your records.
