60 PSI Boost Gauge Installs To GMC Sierra

Black 7 Color 60 PSI Boost Gauge

The 6.6L Duramax 60 PSI Boost Gauge gives you the ability to easily monitor your 14-19 GMC’s boost levels from 0 to 60 PSI and is designed for any Sierra 2500HD or 3500HD running high boost pressure. This turbo boost gauge also ensures your turbo is performing at optimum levels and that it does not overboost causing critical engine damage. A boost gauge is a great fit for monitoring boost levels in your LML or L5P when you’re getting more boost out of your stock or upgraded turbo. This gauge is ideal for newer or modified GMC’s running boost levels in the area of about 30 PSI to 45 PSI.

GlowShift Boost T-Fitting Adapters allow you to avoid drilling and tapping your intake manifold by cutting the MAP line and inserting the T-fitting in the two cut ends. The included hose clamps allow you to tighten the two ends of a MAP line to the T-fitting for an airtight seal which results in extremely accurate boost pressure readings. The T-fitting features a 1/8-27 NPT Female thread for a sensor or compression fittings.

Trans Temp Gauge Compatible With Duramax

Black 7 Color Transmission Temperature Gauge

A GMC Sierra Trans Temp Gauge is essential for any LML or L5P and goes hand-in-hand with monitoring 14-19 Sierra Allison 1000 transmissions, especially when these diesel trucks are towing heavy loads. This gauge allows you to closely monitor the temperature of your transmission, ensuring that it does not overheat causing significant damage. Once you connect the included electronic transmission temperature sensor with 1/8-27 NPT male threads, this Duramax trans temp gauge will take accurate readings from 80° to 260° Fahrenheit.

1500 EGT Gauge For GMC Sierra Duramax

Black 7 Color 1500° F Pyrometer EGT Gauge

The 1500° F Pyrometer Duramax EGT Gauge is essential for anyone driving a 2014-2019 Sierra 2500HD/3500HD who is pushing for maximum output out of their 6.6 Duramax turbo diesel engine. This GMC Sierra EGT gauge will ensure that your exhaust gas temperature is not running too hot which could result in turbo failure, delivering precise readings from 0 to 1500° Fahrenheit. The installation process for the included EGT Probe involves drilling and tapping the exhaust manifold to 1/8-27 NPT and then threading and tightening the Probe.

30 PSI Fuel Pressure Gauge Mounts To GMC Sierra

Black 7 Color 30 PSI Fuel Pressure Gauge

The 30 PSI GMC Sierra Fuel Pressure Gauge for the 6.6 Duramax displays readings from 0 to 30 PSI, and is the right gauge for any 14-19 Sierra since they run on lower fuel pressure. This Duramax fuel pressure gauge ensures your fuel pressure is running at peak levels, and that it is not too low which could result in damage to your fuel pump or injectors. The first step for installation is making sure that your Duramax has an aftermarket lift pump since these diesel engines do not come equipped with one.

Note: When installing this gauge to a GM Duramax engine, an aftermarket lift pump is required for this gauge to function properly. Duramax engines do not have this lift pump to supply fuel to the engine. By adding it, you’ll experience a constant and steady fuel pressure, resulting in increased fuel efficiency, better throttle response, and a smoother idle.
