Answer: If you need to monitor both boost pressure and exhaust temperature in one view, choose a 2-in-1 or 3-in-1 gauge kit designed specifically for diesel applications. These kits simplify installation, provide real-time readings, and help prevent engine damage from overboost or excessive EGT. The top options below are best for performance-minded truck owners, daily drivers seeking reliable protection, and hobbyists who want adjustable lighting to match their dash.
Below is a quick guide to five strong choices that pair boost readings with exhaust gas temperature (EGT) insights. The table summarizes each product’s core focus, best user type, and a key limitation to consider.
| Product | Best For | Key Limitation |
|---|---|---|
| GlowShift 3in1 Analog 60 PSI Boost Gauge with Digital Pyrometer EGT | Diesel enthusiasts needing a compact 3-in-1 view | Analog + digital mix may require familiarization |
| GlowShift Black 7 Color Diesel Truck 3 Gauge Kit | Truck owners wanting color customization | Three separate gauges; dashboard space |
| GlowShift 10 Color Digital Dual 60 PSI Boost & Pyrometer EGT | Clear digital readouts with color customization | 2 gauges to monitor instead of one |
| GlowShift 3in1 Analog 1500F Pyrometer Exhaust Temp EGT Gauge Kit with Boost | Real-time EGT with boost and temp | Analog EGT may be less precise for some users |
| Digital Dual Boost & Pyrometer EGT Combo Gauge Kit (JRP) | Versatile 3-mode display and warnings | Some features are mode-dependent |
GlowShift 3in1 Analog 60 PSI Boost and EGT Gauge
Best for: Diesel enthusiasts who want a compact, single-d unit to monitor boost, exhaust temperature, and temperature trends. The gauge reads 0–60 PSI for boost and 200–2200°F for EGT, with a blue digital display option for the exhaust temp and an analog boost display. The kit includes 1/8-27 NPT electronic sensors and wiring, with multiple color modes to match interior lighting. Caution: mixed analog and digital displays may require calibration during installation to ensure accurate readings.
ZHSYMX Exhaust Gas Temperature Gauge Kit
Best for: Budget-conscious buyers who want an EGT-focused display with alarms. This kit emphasizes real-time engine temperature control and features a red LED display with alarm points and peak memory. It supports a compact form and simpler interface for quick temperature checks. Limitation: It focuses on EGT rather than directly displaying boost pressure, which may require a separate boost gauge for a complete readout.
GlowShift Black 7 Color Diesel Truck 3 Gauge Kit
Best for: Truck owners who want to customize interior lighting to match dash color schemes. This kit includes 60 PSI boost, up to 1500°F EGT, and transmission temperature gauges. The 2-1/16″ (52mm) size fits many factory clusters, and the 7 solid color modes with dimming options help optimize visibility. Caution: All three gauges are separate modules; mounting requires space and planning to maintain a clean dash arrangement.
Digital Dual Boost & Pyrometer EGT Combo Gauge Kit (JRP)
Best for: Diesel owners who want flexible mode options and programmable warnings. This kit provides 0–1800°F EGT and up to 99 PSI boost with a 2-1/16″ dial and 10-color display. It supports three display modes and CPW (Color Pre-Warn) to alert you via color changes and audible alarms before critical levels. Caution: The multi-mode setup may require a careful read of the manual to configure warnings correctly.
GlowShift 3in1 Analog 1500°F Pyrometer with Boost and Temp
Best for: Diesel applications needing a straightforward trio: EGT, boost, and transmission temperature. The 0–1500°F EGT range is paired with 0–60 PSI boost and 68–302°F transmission temp. The 2-3/8″ dial and multiple color modes allow quick visibility and dashboard matching. Caution: This setup emphasizes EGT accuracy, and the fixed 1500°F limit may not cover extreme high-heat scenarios found in certain builds.
Buying Guide: How To Choose A Boost And Exhaust Temp Gauge System
- What readings do you need? If you need both boost and EGT in one unit, prioritize 2-in-1 or 3-in-1 designs. For more data, consider 3-gauge kits that include transmission temperature as well.
- Display type and readability—digital displays offer quick scans, while analog needles show trends at a glance. Some models combine both for quick cross-referencing.
- Color and lighting—color customization helps you match dash lighting and improves visibility in daytime and night conditions. Look for models with multiple color modes and dimming.
- Alarm and warning features—CPW (Color Pre-Warn) or programmable alarms help you detect rising EGT or overboost before it becomes critical. Check for audible alerts and peak memory.
- Sensor compatibility—common 1/8-27 NPT sensors ensure easier installation. Confirm included sensors and wiring align with your engine bay layout.
- Installation considerations—some kits require space for three gauges or wiring harness routing. If you prefer a cleaner dash, choose integrated 1-unit solutions or compact 2-3 gauge pods.
Frequently Asked Questions
- Do these gauges require professional installation? Most kits are designed for simple self-installation, but if you’re uncomfortable with wiring sensors or routing, professional help is recommended.
- Can I use these without a boost pressure source? Some models include only EGT or a separate boost gauge. For a complete setup, choose a kit that explicitly combines boost and EGT.
- What is EGT and why monitor it? Exhaust Gas Temperature (EGT) indicates how hot the exhaust side is running. High EGT can signal engine overheating or inefficient fuel management, risking engine damage.
- Are there color options for better visibility? Yes. Many GlowShift kits offer 7 or 10 color modes plus dimming to fit day or night driving conditions.
- Can these gauges help prevent engine damage? With programmable alarms and real-time readings, they provide early warnings that allow you to adjust driving or fueling before problems escalate.
- What gauge size should I look for? The most common sizes are 2-1/16″ (52mm) and 2-3/8″ (60mm); choose based on your dash space and mounting options.
