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 approximately $2800, 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 Duramax DPF delete?
