Moore Performance in Baltimore: Engine Tuning and Diagnostics for Street and Track

Moore Performance is a independent shop specializing in engine diagnostics, custom tuning, and performance modifications for domestic and import vehicles, located in Baltimore's Fells Point neighborhood. Unlike general repair facilities, the shop focuses on efficiency gains and power output rather than routine maintenance, serving both daily drivers seeking fuel economy improvements and weekend enthusiasts building track cars.

What Moore Performance actually does

The shop handles computer-based engine tuning using dynamometer testing and custom ECU mapping. This means the technicians modify engine control software to optimize fuel delivery, ignition timing, and boost levels (on turbocharged cars) rather than replacing mechanical parts. They also diagnose complex drivability issues like rough idle or check-engine lights that stumped other shops, using advanced scan tools and live-data analysis. The facility includes a in-house dyno for testing power output before and after tuning, which lets customers see measured results rather than feel-based claims.

Moore Performance does not handle general maintenance (oil changes, filters, belt replacement) or collision work. They will not reprogram factory systems into limp mode or disable emissions equipment, which sets them apart from shops that treat tuning as purely cost-cutting. This boundary matters: it signals they prioritize driveability and longevity alongside power.

Services and pricing

Custom ECU tune (bolt-on parts or stock engine): $400 to $700, depending on vehicle platform and complexity. Dyno testing alone (no tuning, diagnostics only): $150 per hour, typically one to two hours for a full baseline and load analysis. OBD2 code diagnosis with live-data pull: $120, applied toward repair cost if the customer chooses to proceed with tuning or repair at the shop.

Turbo and supercharger tuning costs more (verify pricing by platform when you call). Flex-fuel tune (enabling E85 gasoline blends for higher boost) runs $600 to $900. A typical first visit involving diagnosis and a baseline dyno run costs $250 to $350 and takes two to three hours.

How Moore Performance compares to other Baltimore repair options

General shops like Firestone or Jiffy Lube will read codes and replace parts based on diagnostic trouble codes, but they do not modify engine software. For a check-engine light tied to a faulty oxygen sensor, they will swap the sensor; Moore Performance would first verify the sensor is truly bad using live data, avoiding unnecessary parts swaps.

Dealerships offer factory diagnostics and reprogramming but charge $150 to $200 per hour for labor and rarely tune for performance. Their tuning is limited to factory recalibration after repairs.

Select-to-Moore if you want measurable power gains, suspect a tuning issue (rough idle after a modification, for example), or need diagnosis that goes beyond code-reading. Choose a general shop if you need routine service, tire rotation, or brake pads. Choose a dealership if your car is under warranty and you want factory-backed work.

Who it suits and who it does not

Moore Performance suits owners of modified cars (with aftermarket air intakes, exhausts, or turbo kits) who need tuning to match their hardware. It also fits drivers troubleshooting drivability issues that other shops could not solve. Weekend track enthusiasts building 10-second quarter-mile cars find the dyno and data-driven approach valuable for iterative performance work.

The shop does not suit someone looking for basic repairs, tire service, or a quick oil change. It is not the right fit for owners with brand-new cars under manufacturer warranty who want to avoid voiding coverage (though some factory tuning is warranty-safe).

First visit process

Call ahead to schedule a dyno session or diagnostic appointment. Bring any records of recent modifications or work. The technician will connect the car to the dyno, run baseline pulls at wide-open throttle, and capture power and torque curves. If tuning is the goal, they will discuss target power, fuel type (regular or premium), and any drivability concerns (cold-start lag, hesitation, etc.). If diagnosis is the goal, they will pull live data while driving and pinpoint the source of the fault. Dyno pulls take 20 to 40 minutes; total session usually runs two to three hours.

Hours, location, and logistics

Moore Performance operates Tuesday through Saturday, 10 a.m. to 6 p.m.; closed Sundays and Mondays. Verify hours before visiting, as specialty shops sometimes shift scheduling for large projects. Street parking is available in Fells Point, though it fills during peak afternoon hours. The shop is a 10-minute drive from I-83 northbound and a 15-minute drive from I-95 southbound.

Moore Performance fills a rare role in Baltimore's repair market: a shop that owns diagnostic and tuning hardware and knows how to use it without taking shortcuts. Owners of modified cars or anyone stuck on a fault code elsewhere will find the dyno and data-driven approach worth the trip.
