The AutoMeter Spek-Pro 2-1/16" boost gauge reads up to 35 psi for diesel or extreme-boost use and includes a 1/8" NPT pressure transducer plus wiring harness for easier installation. An analog 0.5–4.5V output allows data logging, and a precision 280° brushless stepper motor ensures steady, accurate needle movement. Peak recall stores top readings until cleared, Pro-Control output can trigger external devices, and seven-color backlighting with independent dial and pointer dimming improves visibility.
