They feared it couldn't be done...but can the LP5 Duramax Diesel Engine be deleted? EGR deletes are popular for their ability to increase your truck's performance, emissions, and improve fuel economy. There is much confusion circling the topic of whether the LP5 can be deleted or if GM has found a way to make deleting engines a thing of the past. Let's take a closer look at the robust LP5 Duramax and whether this diesel engine can be deleted and tuned.
The 6.6L V-8 Duramax Turbo Diesel Engine is the creation of General Motors and first appeared in the 2017 Chevrolet Silverado and 2017 GM Sierra HD. It is known as part of the line of new-generation diesel engines, with its predecessor being the 6.6L Duramax V-8 LML.
The LP5 offers the same great qualities as the LML but with distinct improvements in areas that needed it most. These include:
These upgrades from previous engine models allow for improved driving performance, including quicker acceleration, enhanced pulling capabilities, and reduced noise levels. The big question remains. Can this powerful engine be deleted?
While there was much talk and fear of GM designing the LP5 to be undeletable right after its release, these fears have subsided. As predicted by DieselArmy.com, the LP5 was indeed "crackable" and now many owners have successfully deleted and tuned their Chevys and GMs.
GM spent a great deal of time and effort redesigning the control system so that it could not be altered by outsiders in any way, this included deleting the engine. However, in September 2018, HP Tuners was the first to develop a method of infiltrating the engine control module and deleting and tuning the LP5 Duramax. Since then, multiple companies have created products that allow LP5 owners to delete and tune the LP5s in their trucks.
