| Advanced touchscreen monitoring | ||
| Dedicated EGT monitoring | 0–1500°F, LED display | |
| Boost monitoring with style |
GlowShift Black 7 Color 3-Gauge Diesel Truck Set
The GlowShift 7 Color 3-Gauge set combines a 60 PSI boost gauge, a 1500°F pyrometer (EGT), and a transmission temperature gauge in a compact cluster. Best for diesel owners who want a compact, all-in-one monitoring solution with color customization for quick at-a-glance readings. The black dial with a clear lens minimizes glare under daylight. A potential limitation is the need for proper wiring and sensor placement for accurate readings, which may require professional installation.
ScanGauge 3 Touch Screen OBD2 Scanner
The ScanGauge 3 uses an OBD2 interface to deliver digital gauges and a trip computer with WiFi-enabled updates. Best for buyers who want a versatile, compact digital readout without adding multiple mechanical sensors. It excels in data centralization and auto-detection of vehicle diagnostics. Limitations include reliance on OBD2 data availability and potential lag in some readings compared to dedicated analog gauges.
Edge 84130-3 Insight CTS3
The Edge CTS3 Insight offers a color touchscreen display with broad vehicle coverage for 1997–2026 F-150s and various GM models. Best for owners seeking a high-contrast, interactive interface with extensive programmable gauges. This choice is better for tech-savvy users who want customization and on-screen diagnostics. A caution is that advanced features may require time to configure to specific vehicle setups.
Exhaust Gas Temperature Gauge (7 Color Series)
This 0–1500°F EGT gauge provides dedicated exhaust temperature monitoring for diesel trucks with a 2-1/16″ (52mm) dial. Best for drivers prioritizing precise EGT feedback to prevent turbo and piston damage. It’s a straightforward gauge with LED readouts. A limitation is that it measures only EGT, not other engine parameters, so consider pairing with additional gauges for a complete view.
GlowShift Tinted 7 Color 60 PSI Boost Gauge Kit
This kit features a 60 PSI boost gauge with a mechanical hose, compression fittings, and wiring. Best for diesel owners who want a dedicated boost readout with a smoked lens and a separate installation kit. Choose this if you prefer a classic analog display and robust, mechanical-driven reliability. Restriction includes the need for proper hose routing and seal integrity to prevent leaks.
Buying Guide: How to Choose the Right Diesel Gauge Kit
What gauge types do you need? Start with a core set: boost, EGT, and transmission temperature for most diesel setups. Consider adding a digital option (OBD2-based) for centralized data or a touchscreen CTS3 for deeper customization.
Which display style suits your cab? Analog gauges offer quick, tactile readings and simple calibration, while digital displays provide more data and programmable alerts. Color options help reduce reading time in high-stress driving scenarios.
What installation complexity should you expect? Some kits are plug-and-play with minimal wiring, others require sensor placement and routing. If you tow heavy loads or boost pressure frequently, plan for robust sensor mounting and weatherproof connections.
How will you use the data? For performance tuning, prioritize gauges with fast response times and high-accuracy sensors. For routine maintenance, digital data logging and trip metrics can help track engine health over time.
Are there compatibility considerations? Check your vehicle’s model year and engine type to ensure gauge compatibility, especially for Edge CTS3 Insight and ScanGauge models that rely on vehicle-specific configurations.
Frequently Asked Questions
- What is the main purpose of a diesel boost gauge? It measures turbocharger or turbo boost pressure, helping prevent over-boost and engine damage.
- Do I need an EGT gauge if I already have a boost gauge? EGT gauges provide direct insight into exhaust temperatures, which helps protect pistons and turbo components under heavy loading.
- Is an OBD2-based gauge enough for tracking engine health? OBD2 gauges are convenient for core data and diagnostics but may not cover all critical readings like dedicated EGT and transmission temperature.
- Can I install gauges myself, or should I hire a professional? Installation complexity varies; simple plug-and-play kits are feasible for DIY, while sensor routing and calibration may benefit from a pro install.
- Which gauge is best for towing heavy loads? A combined Boost + EGT + Transmission gauge setup offers the most comprehensive monitoring for heavy-duty use.
- How often should I monitor exhaust temperature? Monitor during hard acceleration, towing, or when modifying exhaust/tiring to prevent overheating and potential engine damage.
