HE300VG Stealth Mach 1 (64) Turbo [2019-2024]

The HE300VG Stealth Mach 1 64 for 2019, 2020, 2021, 2022, 2023 and 2024 6.7L Cummins CME is the perfect balance of power, drivability, and reliability. With an upgraded compressor wheel, turbine, and variable geometry nozzle assembly this turbo has the ability to move 30% more air through it than stock. All while providing a better drive/boost pressure ratio than the stock charger. This means not only do you get more power, you also get an extremely fast spool up, comparable to that of the stock charger. If you tow or haul heavy loads on a regular basis this is the turbo for you. Quick spool up means taking off from stops is a breeze and the ability to retain your factory exhaust brake makes braking easier and saves your brake pads. Plus our upgraded turbine wheel and HFV technology help to lower EGTs which gives you even more confidence when towing a heavy load up a steep grade. To top it all off this turbo comes with a brand new genuine HE300vg Holset actuator to ensure proper operation. 

The Stealth Mach 1 64 HE300VG has undergone testing to demonstrate that it complies with federal emissions regulations. This testing provides the reasonable basis required by the standards defined by the EPA. Here you can find a PDF which documents this testing.

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.
