5.9 vs 6.7
 

I need to replaced my truck that burn down, it was a 2004 with a 5.9. I see some 6.7 for sale and my concern is that I do my own mecanic and the 5.9 is a very good engine and the parts a easy to found and I am scare to switch to the 6.7. What is the good and the bad about the 6.7, and whats the uprade to make to make it good.

Emission stuff is really the issue with the 6.7. If its a 07.5-09 you can delete it with a few parts and EFI Live

2010 are don't seem to have the problems the 7.5-09 but then the 11 had same issues it seems like12 got better. 10 were easy to delete w/mm. I've had no problems other than oil pressure sender gauge

I have a 2011 4x4 with a manual trans, it's a great rig so far. But I feel the emissions choke it down. Just waiting for the warranty to run out, so I can do some deleting.
