I bought a used 2009 Silverado 2500HD with a Duramax LMM earlier this year from a local used call dealer. This month, I failed emissions and discovered the truck has a CAT and DPF delete kit in it. I purchased the parts to reinstall the CAT and DPF and was planning to use my HPTuner to re-enable the Regen Cycle, but learned that they removed this functionality from the software.

I was just about to order the EFILive Flashscan V2 tool and decided to Google the DPF functionality. I found a post in the LML forum indicating the tables for this setting don't exist in the U.S. version. Does anyone know if this is only for LML or has it been removed from the LMM software too?

I really feel stuck here, my tags expire in 9 days and I cannot register my truck until I can get it through emissions.
