The day has come that many thought would never be. PPEI is proud to announce our release of EFILIVE for the 2011-2015 LML Duramax. We know that many have been asking for this time and time again, and it’s finally here. With the addition of EFILIVE to our tuning arsenal on the LML, we are able to better tune in drivability, as well as some monster combinations that are soon to hit the streets. At this time, we will begin taking orders for immediate fulfillment. The AutoCal device comes preloaded with 5 tunes for your vehicle and combination which level of tuning depends on the mods of your truck:

Stage 1-Stock or built transmission, Stock turbo, Stock injectors

 This is not meant to be a “better” tuning option than our MCC files, but rather another option for tuning. We strive to give our customers more options to reach their end goal with their vehicles. This is just another avenue to reach the same goal, more power with better economy. No matter the modification, we can tune for it. Rather it be exhaust, dual pumps, injectors, or different turbo applications, we can tune for whatever you need right here in America!
