6.7 vs 6.4
one of my good friends is a die hard cummins guy and he has always had the upper hand when it came to big hp trucks and i have always been the under dog with my 6.0l, at least until the introduction of the 6.4l and he is scared of it, i will tell him about 500+hp 6.4l with only exhaust and tuning. and he refused to believe that the stock fuel system and or trans couldn't handle it, until the magazines and you tube started backing me up and now he has been making up lies, first one he told me one of his friend works for ford and says the 6.4l is a piece of ****, just wondering if anyone has herd anything bad about the 6.4l besides the poor poor mpg, next he said he found a race between a 6.7l with dpf egr delete water/meth 90hp sticks a fully built tranny smarty and dr.p box, 6.4l has dpf egr delete with a 320hp tune, i do a lot of research about 6.4l and don't know if anyone has a 320hp tune just wondering if anyone know who is or has seen this supposed video. sorry about the long post not really looking for input just kinda venting, my g/f doesn't care to here about it anymore. can't wait to get my 6.4l so i can strait up show him what the 6.4l is all about.
