The day has come that many thought would never be. PPEI is proud to announce our release of SOTF EFILIVE for the 2011-2016 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. The AutoCal device comes pre-loaded with a SOTF Tune for your vehicle and combination which level of tuning depends on the mods of your truck and a stock file if requested.

This tuning allows you to switch between five different power levels via a DSP switch wired to the ecm.


LML power levels ( Stock Trans ): Engineered for trans safe tuning.


Power levels consist of ( most popular tunes ) HP increments over factory HP.

• Optimized Stock 30 HP

• Tow 60 HP

• Street 100 HP

• Race 150 HP

• Maxx Effort 200+ HP (Requires you to have a lift pump)


Note* the 2015 + LML Duramax trucks will not come with a stock A_Flash file unless the file is requested. There is no fee for the A_Flash to be sent at a later date.
