05:23 Tow Test
22:51 Spool-up Test
25:51 Peak Power Test

Nick Priegnitz and the Calibrated Power / DuramaxTuner's R&D team dive into the most extensive turbo testing and analysis for the 2003-2007 5.9L Cummins. Using our chassis dyno, EFiLive Tuning, and 20+ years of experience, Nick compared a Stock, Stock w/Wastegate Mod, and the 5.9L Cummins STR turbo on our 2007 Ram 2500 HD. Nick chose to monitor and log data utilizing the Gale Banks (Banks Engineering) iDash and our in-house Mustang Dyno.

Nick covers the details we found through days of dyno testing. Air-to-Fuel-Ratio, Drive Pressure, Shaft Speed, EGT, Boost, Towing Performance, Spool-up, and of course peak horsepower (with and without lambda limits) are all broken down in an easy-to-follow and easy-to-understand format.
