I am a newbie to this forum and i have a few question that I'm hoping someone can answer. I have a 2007 LMM with a bully dog tune install. I purchased it to observe how many regeneration my truck has. I don't drive the truck much and it goes into a regeneration twice a month ( every 400 km ) I have 80,000 KM on truck. I'm thinking its time for a new DPF. I was wondering if I removed the DPF and with a straight pipe and reinstalled the bullydog tune to a 2007 LBZ tune. Do you think there would be any problem with this???
