Default Best Options and Experiences With Full Delete Kits for L5P Duramax?

Hello everyone.

I’m researching upgrades for my L5P Duramax and would like some real-world feedback from other diesel owners. I mainly use my truck for towing and highway driving, so reliability and performance are both important to me. I’ve seen several delete kits online, but it’s hard to know which brands are worth the investment and which ones cause issues later.

I recently came across the specific full delete kit for L5P Duramax from EGR Performance and wanted to know if anyone here has installed it. How was the installation process, tuning compatibility, fuel economy, and overall performance after the upgrade?

Any advice or recommendations would really help.

If I was serious about Deletes. I would go to a shop that works on these systems because they know the ins and outs to these kits that are for sale. These Kits will all say off road only as a disclaimer. Their are the off Roader 4wd fourms fourms that might be helpful. Sorry I'm not much help but that is what I would do if I was going to do a delete.
