This has many boat owners wondering how to tune their engines so they can get more hours out of a tank of fuel, while at the same time improving overall efficiency.

Striking Looks, Real-Time Feedback
The digital gauge panel brings a sleek new face to your truck interior—think bold LED read-outs, crisp graphics, and that aggressive dashboard presence your build demands. Speedometer capacity hits 255 MPH, the tachometer sweeps up to 9,900 RPM, and fuel, oil pressure, and water temperature readouts are instantaneous and accurate. With the smoked plexiglass faceplate, you get a stealth-look interior that screams pro-level craftsmanship.
Tech That Works as Hard as You Do
This isn’t just a visual upgrade—it’s a performance-driven instrumentation solution. One-button speedometer calibration works across any tire size, gear ratio, or transmission type. Senders for oil pressure and water temp ensure you’re reading real data, and the panel handles mechanical or electronic transmissions with ease. For builders running modern swaps, it’s plug-and-play capable and ready for serious duty.
Premium Upgrades for Next-Level Builds
🎨 Custom Colors – For enthusiasts who want to dial in a personalized look, the Intellitronix analog gauge panel offers seven vibrant LED color options—blue, green, red, white, teal, orange, and pink—so you can match your dashboard glow to your build’s vibe. Whether you prefer a subtle white backlight or a bold teal pop, the color options let you fine-tune your interior aesthetic without sacrificing performance or readability.
⚡ Universal Gauge Harness — Clean, pro-style wiring made simple: an 8-foot color-coded harness with quick-connects and full support for water temp, oil pressure, tach, voltmeter, fuel level, speedometer, dash lights, turn indicators and high beam.
