Stealth Boost Tester - LLY, LBZ, LMM, LML Duramax - VVT Faceplate Adapter

Does your diesel have High EGTs, Excessive SMOKE, Increased Turbo Lag, and Less Power than it used to? 

Let’s talk about boost leaks. Your truck needs air! Not a little bit of air. Your diesel engine needs all the incoming air it can get. Increasing air in the combustion process will help manage your Exhaust Gas Temperatures, limit your smoke output, and increase your power. This is why boost leaks kill diesel engines. Boost leaks can result in a smoky, laggy, dog-of-a-truck that runs hot and burns excessive fuel. Basically, the exact opposite of what you want from your diesel. Boost Testing your diesel is essential! Every truck that comes in the shop, gets a boost test. It seems about 85% of them have a boost leak when they show up. Most of the time customers report still seeing peak boost on their gauges despite a boost leak. However, common symptoms of a boost leak include Increased Smoke, Higher EGTs, Excessive Lag, and Loss of Power. If you work with diesel trucks long enough, you’ll see leaks just about everywhere in the charged air system at one time or another. Remember, the charged air system includes anywhere from the turbocharger to the intake manifold.

Your Intercooler system, Exhaust Gas Recirculation components, and even the turbocharger compressor cover can all develop boost leaks. Over the years, our team has used just about everything you can think of to boost test a truck. From PVC pieces to smoke testers, and just about anything else you can think of. There are a few kits out there that will help, but nothing that truly tests the entire system accurately and is made of premium parts. That’s why we invested the resources to develop the Stealth Boost Tester. You can now easily and accurately test your entire charged air system. The kit is made entirely of premium parts, designed to last, and built to rigorous standards. The 2004.5-2016 6.6L Duramax Boost Test Kit is a billet adapter that connects directly to the face of your Turbocharger Compressor Inlet with supplied stainless steel v-band clamp and high quality o-ring seal.

Removing a Cold Air Intake in most trucks is a job that only takes a few minutes and requires the most basic mechanical skill.The same goes for installing and using our boost leak test kits. The Stealth Boost Leak Test Kit Compressor Inlet Adapter features a conveniently placed swivel fitting, allowing them to work with our high-quality HD Regulator (sold separately).

The regulator is a crucial component when using the kit. If you have ever used a bad or failing regulator, you know how frustrating it can be. Our Stealth HD Regulator is made from high-quality materials designed to last. The unique advantage of this setup is that it allows you to accurately test the entire charged air system of your engine very quickly. Developed from years of hands on experience with these trucks as premium tool that's easy to use and provide accurate results. If you’re interested in boost testing your turbocharged vehicle, we most likely have a kit for you.
