Blessed Performance for the Duramax Tuner Stealth STR Drop In VGT Turbo for 2017 to 2023 L5P Duramax diesel trucks.
The L5P Stealth STR is the best replacement turbo for your stock 6.6L L5P or L5D Duramax. While capable of providing enough airflow to support up to 625 RWHP, this stock-appearing unit still lights quickly and is great for daily driving, towing, and while providing better than stock performance.
If you have been looking at other "64mm", "Stage 1", or stock turbo replacements this is a game changer. This turbocharger does not need custom tuning or other upgrades to get superior performance. Box programmers and inline modules work seamlessly with the L5P Stealth STR.
Don't be fooled by the imitators! Calibrated Power Solutions / Duramaxtuner have been building custom turbos and providing custom tuning for more than 15 years. They were the first custom tuners to work on the L5P Duramax platform together with us and know exactly what these trucks need to go to the next level.
