Quick video of a 2 year review of my L5P Duramax, what led me to this vehicle, and what some of the drawbacks have been. In totality there hasn't been much....The Chevy and GMC 6.6 Duramax is a great engine with some proper modifications to address trouble areas. If you have any questions about performance modifications or selecting repair parts for the Duramax, please feel free to give us a call at 1-877-367-9351.
