The AutoMeter Spek-Pro 2-1/16" boost gauge reads to 35 psi and is suited for diesel or extreme-boost applications, with an included 1/8" NPT pressure transducer and wiring harness for easier installation. It provides an analog 0.5–4.5V output for logging, smooth needle control from a 280° brushless stepper motor, and peak recall to retain the highest reading. Pro-Control output can drive external warnings, and seven-color selectable backlighting offers independent dimming for dial and pointer.
