Calibrated Power Solutions, the company behind DuramaxTuner.com, is a diesel calibration shop founded by Nick Priegnitz. It grew up in Marengo, Illinois, and now works out of Woodstock, Illinois, where it runs a full-service diesel performance and repair shop with a 4WD chassis dyno. The company has built its name on emissions-intact power.
What we carry
We stock Calibrated Power parts for Duramax, Cummins and Powerstroke trucks from 1991.5 to 2024:
- Stealth drop-in turbos in STR, Mach 1 and Mach 2 tiers, plus the Stealth DT44 for the 2.8L Duramax. STR runs on stock tuning. Mach 2 needs custom tuning.
- DT750 Built Allison 1000 transmissions with torque converter for Duramax.
- Stealth Boost Tester regulator, compressor inlet adapters and faceplate adapters.
