I just bought a 2015 Ram 2500 with 50K miles on it, as far as I know its all stock, never any Tuning and all Emissions are still intact. Can anyone point me in a direction for Emissions Compliant Tuning? Meaning still using all Emissions on the truck. Just looking to up the HP and Torq. If not able to do that, can someone explain to me why and what would be the benefit of going Partial delete or full delete. Also I'm looking at putting a K&N Filter with the Straight pipe (not the Accordion) extension from air box to turbo, along with the CCV delete, well to a catch can, will this throw a code if I don't have tuning?
