2-1/16 Boost Pressure Gauge - GM Diesel Truck

The 2-1/16 Boost Pressure Gauge - GM Diesel Truck by AutoMeter is a direct-reading instrument designed for diesel engine builders and owners who need real-time boost monitoring on their modified trucks. Whether you're running a stock tune or a custom ECU tune with aggressive boost targets, this gauge delivers critical turbocharger pressure data to your dashboard or engine bay, allowing you to dial in performance safely and verify that wastegate and turbo response stay within safe parameters.

Engineered specifically for GM diesel applications, this 2-1/16-inch gauge features a mechanical pressure sensing element that responds accurately across the full boost range without electronic interference or lag. The face is calibrated in PSI, making it intuitive for tuners monitoring peak boost levels and transient spikes during acceleration and load conditions. AutoMeter's construction delivers reliable, repeatable readings even in the vibration-heavy environment of a diesel engine bay, where thermal cycling and fuel system pressure can stress lower-grade gauges.

GM diesel truck owners benefit most from this gauge during tune verification, boost creep diagnosis, and turbo upgrade validation—whether you're running a 6.6L Duramax, 6.5L Power Stroke conversion, or aftermarket turbo package. Installation requires a boost line source from the intake manifold or intercooler outlet, making it compatible with both stock and heavily modified induction systems. The compact 2-1/16-inch diameter fits standard gauge pods, A-pillar mounts, or custom dash panels without requiring extensive modification, making it ideal for both street trucks and purpose-built competition diesel platforms.
