Ok before u get all sorts of crap for asking a question that a lot of folks have already asked, I recommend at least tryin the search button.
Without typing my fingers off, 2010 is the best year of the 6.4 IMHO. It was the last year of the 6.4 before 6.7 man. If u delete the Dpf and egr and tune her with spartan or H&S, it is te most reliable truck On the road. Do some research big dawg. U will find what u need to know.
My opinion is do it, delete, and don't turn back! I went from a 6.0 to a 6.4 and it's been the best decision ever. DO IT!
