Don't Just Replace Your Stock L5P/L5D Turbo!

There's no better feeling than getting to upgrade your parts instead of just replacing them. That's exactly why Calibrated Power made the Stealth STR for 2024 and 2025 6.6L L5P Duramax's. Designed to improve turbo performance and reliability while still coming in around the cost of a stock turbo replacement.

The STR has also been designed with easy tunability in mind. Unlike other "drop-in" upgrades that require much more than just dropping in a turbo to get up and running. The STR requires no custom tuning to get up and running and has been designed to be as simple to tune for as possible. Say goodbye to lengthy tuning and multiple tune revisions!

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.
