Boost/Vacuum Gauge keeps you informed on manifold pressure so you can see how your engine responds during idle, cruising, and acceleration. Track vacuum for efficiency and engine health, then watch boost build under load to understand performance in real time. Built to show how your engine is behaving across the full range, it helps you catch leaks, tuning issues, or inconsistencies early. A built-in warning light alerts you when pressure moves outside your set range for added protection. A precision stepper motor keeps the needle smooth and steady—no bounce, no guesswork. Built with a durable housing and solid aluminum bezel, it’s made for real driving conditions and long-term use. Made in the USA and backed for life.

Track-Tested. USA-Built. Backed for Life.
