The AutoMeter Spek-Pro 2-1/16" vacuum/boost gauge (–30 inHg to 30 psi) helps gasoline-powered forced-induction systems stay within safe limits, with circuitry that auto-calibrates at startup for altitude and barometric shifts. Included MAP sensor and wiring harness ease installation, while a 280° brushless stepper motor offers precise needle movement. Peak recall holds top readings for later review, Pro-Control can trigger external devices, and seven-color selectable illumination with independent dimming improves readability.
