    DPF Deletes legal now? EPA Rescinded 2009 Endangerment Finding 3.0 Duramax Podcast 10

    Did the EPA just make diesel deletes legal? Over the last few days, headlines about the 2009 Endangerment Finding being rescinded and auto start/stop credits being removed have caused a lot of confusion in the diesel world. Many 3.0 Duramax owners are asking whether emissions rules were rolled back and whether DEF or DPF systems could be going away. In this episode, I break down what was actually rescinded, what it means legally, and — just as importantly — what it does NOT change. We discuss: • What the 2009 Endangerment Finding was• How greenhouse gas regulation differs from diesel aftertreatment standards• Why the Clean Air Act still matters• What the anti-tampering provision means for deletes• How Right to Repair fits into the conversation• What would actually have to happen for emissions removal to become legal• And what 3.0 Duramax owners can realistically expect moving forward I also share real-world experience from my 2024 LZ0 and how calibration updates are quietly refining the platform year over year.
