CALIBRATED POWER STEALTH MACH 1 (64MM) TURBOCHARGER CPS200226 | 2001-2004 6.6L DURAMAX LB7

Upgrade your GM 6.6L Duramax LB7 with the Calibrated Power Stealth Mach 1 Turbocharger. Designed as a direct drop-in performance upgrade, the Stealth Mach 1 builds on the factory turbocharger configuration with increased airflow, faster spool-up, and improved efficiency while maintaining the drivability needed for daily driving and towing.

At the center of the Mach 1 is a 64mm billet extended-tip compressor wheel. Manufactured from billet aluminum for strength and durability, the upgraded compressor is designed to move more air than the factory turbocharger while providing responsive boost characteristics across the operating range.

The compressor is paired with an optimized high-flow turbine design that improves exhaust flow and efficiency. The upgraded rotating assembly helps reduce turbo lag, sharpen throttle response, and maintain consistent boost response under load, making the Mach 1 well suited for street-driven and towing applications.

The Stealth Mach 1 installs as a direct replacement for the factory LB7 turbocharger and maintains a stock-appearing installation. Each turbocharger is assembled using brand-new components throughout, eliminating the need for a core return or core charge.
