Hey guys I need some help I'm debating on getting a new truck and I can't decide weather I want a 6.4 or a new 6.7.

Can yall please help me out by giving me some pros and cons about the two trucks.

I would like to program the one I get and put an exhaust and some other goodies so I would alos like to know are these trucks bad like the 6.0's if their programed ?

Thanks a lot

 

I Love the way my 6.4 runs.(like a striped *** Ape!) But mine has not got very good mpg since i put the programmer on,and took the DPF off.

 

What kind of mpg are you gettin and what programmer and tune are you runnin on your truck?
