We often get a ton of questions regarding what we would do with necessary upgrades for the LML Duramax. We figured we'd bring in one of the Calibrated Power Shop Techs, Nick Evertsen, to answer that question. Nick has been a GM tech and moved around to independent diesel shops to arriving over at Calibrated Power now. He is taking his decades plus amount of expertise to answer the question, 'Top five reliability upgrades for the 2011-2016 6.6L Duramax.' These trucks are now between 10 and 15 years old(insane to think), and we have the best upgrades that will keep your LML running optimally and for the long haul. Enjoy!
