2017-2019 Duramax Stealth Mach 2 67 Turbocharger (DM1JK1070303000)

Description

Fits

High Flow Vane technology is Calibrated Power's 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 HFV upgrades are capable of producing more power, spooling up quicker, and managing EGTs better than those limited with factory nozzle rings.

Notes

• This turbo uses a customized nozzle ring and/or shroud plate.  It’s been engineered to provide amazing response and performance. 
• This turbo must only be operated with tuning that uses stock Minimum and Maximum Vane Position tables. Failure to do so can lead to excessive exhaust pressure and boost which may shorten the life of the turbo or engine and may void the turbo warranty.
