I want to run 5 inch stacks again and run a cold air and edge with juice attitude. But i see alot of problems with this new motor. What all should I do. I really want a new diesel but the 5.9 seems to be a better motor but i may be wrong. Will it run like my o4.5 325 610 motor with the same mods or will it be better. All advice welcome.
Thanks

 

My 6.7 runs great with nothing done to it. I am Just waiting to see what is out there before i get something.

 

I think you will be impressed with the 6.7 Ive ran a powerpup on mine since 1200 miles and havnt had any trouble out of it
