I have seen a bunch of bulletproof kits and other things out there to try and fix some of the factory motor problems. I am not running a chip at all. Has anyone installed and seen any success with any opf these kits?

Cummins is the fix.

Whats broken ? I have 3 with over 150k on them .
Friends Cummins has had a few drive train issues but I'm good .

I asked a mechanic buddy of mine what I should do with my 2007 coming out of warranty. He said forget all the kits.......just spend the money on an extended warranty.

Sell it! J/K.

What ever you do dont trade up to the 6.4

Why?

cooling problems with mine just had to put a new radiator only 34000mi lots of pulling power think it will be ok when i get it all fixed hope so

Blows my mind how some of these motors are bullet proof and others have been nightmares for the owners.

Trade down to a 7.3 or a dmax.
