LHHPerformance

High-end ECU tuning and precision car audio. We calibrate performance software and build sound stages.

No shortcuts. Just science.

Most places just load up generic software or swap in basic speakers. We treat every car like it needs careful engineering.

Our work is based on real data, thorough testing, and proven automotive principles. We measure everything, analyze the results, and fine-tune using professional tools built up over years of experience.

How We Work

Everything gets measured. We don't guess at what will work. We test and verify every change.

Your safety comes first. We keep all the safety systems working and never push beyond what's safe.

We check back with you. A month later, we follow up to make sure everything is still running great.

The right tools for the job. We use professional equipment designed for automotive work.

Our Approach

We started as automotive technicians who wanted to do things right. Each project gets the same careful attention to detail that you'd expect from a professional workshop. We focus on getting real, lasting results that you can count on.

Real talk on results.

We're often asked why we don't just "flash and go." The answer is simple: every engine has its own history and every cabin has its own rattles. A generic approach is a gamble we aren't willing to take with your car.

Engine Longevity

Power is useless if the engine fails in six months. We prioritize thermal management and fuel ratios over absolute peak numbers. A safe tune is a fast tune that lasts.

Acoustic Balance

Great audio is about balance, not just bass. We spend as much time on time-alignment and EQ as we do on the actual install. The goal is a soundstage that feels like the music is right in front of you.

Testing & Logs

We use professional data logging on every project. It's how we find small issues before they become big problems. If the logs don't look perfect, the car doesn't leave the shop.

Our Standards

We treat your car like our own. That means no cut wires, no broken clips, and no hidden shortcuts. We're proud of what's under the panels, not just what's on the surface.
