2017 GMC Denali L5P Duramax First Dyno Runs

We got our new L5P Duramax yesterday and 10 minutes after arriving with 70 miles on the clock it was on the Dyno. Stay tuned as we do more work on the platform. If you have questions about building and where to get parts for your diesel truck, please send me a email to Jim@duramaxtuner.com
