2017-2023 Duramax L5P Stealth Mach 2 Turbocharger (CPS200362)

Fits

The Stealth Mach 2 67 VGT Turbo is an upgraded stock-appearing direct replacement turbocharger for 2017-2023 Chevrolet Silverado and GMC Sierra HD trucks with the 6.6L L5P Duramax diesel engine. Also compatible with 2019+ L5D applications, this turbo is built for quick spool-up, EGT control under heavy load, turbine braking during towing, and serious power potential.

With Calibrated Power Solutions' proprietary HFV High Flow Vane technology, an oversized turbine wheel, and a custom billet compressor wheel, the Stealth Mach 2 67 supports up to 650 RWHP with emissions compliant tuning and basic supporting modifications, with 800+ RWHP verified in competition applications with extensive supporting mods.
