What would be the cheapest route for tuning a 6.7 Cummins in a 2013 Ram 2500 that still has DPF EGR and SCR? I don’t want to delete the truck I only want a single event 12 valve tune for it that will be clean and reliable as to not plug my DPF. It will be strictly for warm weather useage the truck does not get driven in the winter. I do not have a tuner for the truck so any advice on what tuner to get and how to get a 12 valve tune would be appreciated. I don’t care about power or fuel mileage gains I just want the sound.
