Fly Under the Radar! 2004.5-2010 Duramax Turbo Upgrade
Building this line of Stealth's meant designing a turbo that would be safe to tow with, fun to drive every day and perform at competitions. If you think street-able, clean, stock-appearing power is cool, then this is the turbo for you!
The VVT Stealth 67G2 takes a stock appearing LLY/LBZ/LMM turbocharger and overhauls it to be the Ultimate Duramax VVT drop-in. This means your new turbo will spool-up quickly, feel responsive, and most importantly will move for air into your engine! That means more top-end power without sacrificing driveability.
This turbocharger features HFV technology! HFV or High Flow Vane technology is our proprietary customization of the variable vane cage and nozzle ring assembly. This advancement allows the use of a larger turbine wheel for maximum high-load efficiency. Stealth turbos featuring our HFV upgrade are capable of producing more power, spooling up quicker, and managing EGTs better than those limited with factory nozzle rings.

Add on a Stealth Boost Tester.
Boost leaks can kill diesel engines. They cause higher EGTs, decrease your power, and lower fuel economy. Properly being able to test your entire charged air system is essential to getting peak performance and longevity out of your diesel engine. Charged air systems include everywhere 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. This boost tester is exactly what you need if you work on diesel trucks regularly or just want to check the condition of your engine's charge system. Here's what you can get:
