Calibrated Power 10-12 6.7L Cummins Stealth Series 64mm Turbo

Bolt-on, upgraded turbo for your 6.7L Cummins CMD (2010, 2011, 2012). Excellent EGT control makes this a great turbo for towing and the extra power will make your truck more fun to drive! You'll love the "whistle".

Featuring HFV (High Flow Vane) Technology!

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.

Upgrades to this turbo include Calibrated Power's proprietary HFV technology, a larger turbine wheel, a billet compressor wheel, a genuine 351ve Holset actuator, and more. Excellent EGT control makes this a great turbo for towing and the extra power will make your truck more fun to drive! You'll love the "whistle".

*This turbo requires custom engine tuning

We have developed specific instructions and Min/Max vane position tables for custom tuners in order to aid you in getting the greatest benefits from this turbocharger. You should expect to work directly with your tuner to dial in a calibration that is perfect for you.
