The phrase refers to local automotive service centers equipped with a dynamometer, a device used for measuring force, moment (torque), or power. These establishments offer diagnostic and tuning services, providing quantifiable data about a vehicle’s engine performance. For example, an individual experiencing decreased horsepower might search online for these types of specialized shops to diagnose the issue.
Locating a facility that can accurately measure engine output offers significant advantages. It allows for precise diagnostics, identifying areas where a vehicle’s performance may be lacking. Further, the data derived from a dynamometer facilitates customized tuning adjustments, potentially optimizing engine efficiency, increasing power, and improving overall drivability. Historically, dynamometers were primarily used in research and development settings, but their accessibility for consumer vehicle modification has increased significantly.
