I am new to the dodge world and need some expert advice. I am looking to buy either a 6.7 or a 5.9. If I do the 6.7 it would have to stay stock for warranty or would it be better to mod a 5.9? I am coming from a 6.0 so I'm just worried about any issues. Thanks in advance!

 

you will be moving up either way you go haha but jokes aside. if your wanting to keep a 6.7 stock you will be much happier with a 5.9. on the 6.7 if you just delete all the emissions b.s they are great trucks aswell

 

It really depends on what you use the truck for as to which one is best for you. The 5.9 has better HP potential if you can find a good one. The 6.7 is a great truck overall but has head gasket issuse if you push them hard. Emissions on the 6.7 is easily removed and makes the truck run the way it should. Modifying the 6.7 will void the warranty but they are pretty good trucks if your not pushing them too hard. It all goes back to what you need and what you want. Good luck.

 

i was in the same delima as you and i said screw it and decided to go with a new 6.7 and absolutely love it! and im doing all the deletes as well on tuesday and cant wait to get my new truck again hahaha definately go and test drive a new 6.7 and let me know how you like them!
