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.

Boost leaks can result in a smokey, laggy, dog-of-a-truck, which runs hot and burns excessive fuel. This is why boost leaks kill diesel engines.

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.

You can choose either a Compressor Inlet Adapter or Turbo Faceplate Adapter to go along with your kit.

The S300 Compressor Inlet Adapter is a billet adapter that connects to your Compressor Inlet with a heavy-duty, 4ply boot, and 2 high strength T-Bolt clamps. 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 the Compressor Inlet Adapter. Your billet adapter even comes with how many inch-pounds the T-bolts need to be tightened to.

The Compressor Inlet Adapter for S300 turbos features a conveniently placed and sealed fitting, allowing them to work with our high-quality regulator. This 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. You’ll notice the liquid-filled gauge here. That prevents erratic reading from pressure spikes and external vibrations. And of course, the regulator made from high-quality materials designed to last.

The unique advantage to this setup is we can accurately test the entire charged air system very quickly.

I know our mechanics like it because they prefer to use premium tools that are 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.

This vehicle fits the S300 turbo only.
