Boost Testing your diesel is essential!  Common symptoms of a boost leak include Increased Smoke, Higher EGTs, Excessive Lag, and Loss of Power.  Every truck that comes in our shop here at Calibrated Power, 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. 

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 an Intake Horn Adapter or Turbo Faceplate Adapter to go along with your kit.

The Intake Horn Adapter is a billet adapter that connects to your Intake Horn with a heavy-duty, 4ply boot, and 2 high-strength T-Bolt clamps. This is a great option for someone with an LB7. 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 Intake Horn Adapter. Your billet adapter even comes with how many inch-pounds the T-bolts need to tighten too.

The Turbo Faceplate Adapter connects directly to the inlet of the turbocharger.  If you have a sheet metal intake that’s not designed to hold compressed air or a brand new turbo upgrade, you may prefer this option. Just as the name implies, the billet adapter connects directly to the face of your turbocharger.

Both the Intake Horn Adapter and Turbo Faceplate Adapter feature 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.
