There were doubts that it was impossible… but can the LP5 Duramax Diesel Engine be deleted? EGR deletions have become a popular choice among truck owners, offering enhanced performance, better fuel economy, and improved emissions control. However, there has been a lot of confusion surrounding the LP5 Duramax—specifically, whether it can actually be deleted or if GM has made it completely untouchable. Let’s dive deeper into this powerful engine and explore whether it can be modified and tuned.
The Launch of the LP5 Duramax
The 6.6L V-8 Duramax Turbo Diesel Engine was introduced by General Motors in 2017, making its debut in the Chevrolet Silverado and GMC Sierra HD models. It marked a new era for GM’s diesel lineup, succeeding the LML Duramax V-8. The LP5 was designed with performance, efficiency, and reliability in mind, setting a new standard for heavy-duty diesel engines.
What Makes the LP5 a Step Forward?
The LP5 brings several key improvements over its predecessor, the LML. These enhancements include:
- Stronger cylinder block and rotating assembly for increased durability
- A newly developed GM control system for better performance and monitoring
- 90% of peak torque available at just 1,550 RPM, improving low-end pulling power
- A redesigned camshaft profile for more efficient combustion
- Enhanced cylinder head design for better airflow and cooling
- Higher cylinder pressure capability for more power output
- Lower emissions due to advanced engineering and technology
These upgrades not only improve driving performance but also offer smoother operation, better fuel efficiency, and reduced noise. But the big question remains: can the LP5 Duramax be deleted?
Is the LP5 Duramax Deletable?
When the LP5 first launched, many feared that GM had made it impossible to delete. However, those concerns have largely been proven unfounded. As predicted by experts like DieselArmy.com, the LP5 was indeed crackable, and numerous owners have successfully deleted and tuned their trucks.
GM invested significant resources into redesigning the engine’s control system to prevent unauthorized modifications, including EGR deletions. However, in September 2018, HP Tuners became the first to develop a method for accessing and modifying the LP5’s engine control module. Since then, other companies have followed suit, offering reliable deletion and tuning solutions for LP5 owners.
