Frequently Asqued Questions

What do I need to delete my L5P Duramax?
To delete your L5P Duramax, you'll need a complete emissions delete system, starting with a high-quality L5P delete kit. Solutions include LML, LMM, LB7, LLY, LBZ, and LM2 delete kits, as well as full Duramax delete kits for specific setups like the 2015 or 2016 Duramax. Adding a Duramax EGR delete kit and a reliable Duramax programmer can further enhance performance.
Should you delete your L5P Duramax?
Deciding to delete your L5P Duramax depends on your performance goals and vehicle usage. Many enthusiasts choose deletion to increase power and reduce maintenance. However, local regulations should be considered before proceeding.
How much does it cost to delete an L5P Duramax?
The cost of deleting an L5P Duramax is around $3,400, though it can vary depending on the parts and tuning required. Investing in a premium delete kit, complementary systems, and a Duramax programmer ensures quality and performance.
Is it illegal to delete a Duramax?
The legality of deleting a Duramax depends on local and federal emissions regulations. Deletion can boost performance but may be illegal for on-road use in some areas. These products are typically intended for off-road or racing applications.
Do I need a tuner for a DPF delete?
Yes, a tuner is highly recommended for a DPF delete because removing the diesel particulate filter requires precise recalibration of the engine's computer.
Can a 3.0 Duramax be deleted?
Although Duramax usually refers to larger diesel engines, some variants like the 3.0 Duramax may also be candidates for deletion. Expert advice should be consulted to determine the correct delete kit.
