This has been true ever since they got rid of the 7.3!
My friend, Matt, was assigned, along with about 4 or 5 other guys to sort out all of the issues (engineering consulting firm). When they told Ford the issues were not electronic, they were fundamental to the design of the engine, Ford told them to patch it up as best they could. He says the 6.4 is even worse than the 6.0 that Ford pulled off the market after a few years.

Funny you are still brand loyal... My viper didn't make it 2 miles from the dealer before I had to take it back because the tie rod ends were left loose.... Quality for sure...
Chris sweet truck .... diesels are a blast when you chip them and unleash a shit load of torque. It runs mid 14's to low 14 with 4 tool boxes in it, topper, brush guard. I could take all sorts of stuff off and run way faster, but that is the fun of it...running fully loaded.

6.0 issues were blown outta porportion, we have a fleet of them in the family for various businesses, friend has one of the largest electrical contracting firms with a whole fleet, and others we know who used for personal use...and they've been great. I had to borrow uncles the other day to tow, he has just over 150K on his 04' runs like new.
From what I understands the motor was fine, it was the crap electronics Ford used that was causing issues for the people who ended up having trouble. Navistar far as I know had great reliability from the 6.0 when used with their configuration.
I love the smoothness and power of the new 6.7 Cummins when paired with the 6 speed auto (was mandatory to have the manual trans with the 5.9, the 5.9 and 4 speed auto was a shitty combo when towing or even normal driving), but the 6.7 drinks like a gasser.
I was looking at some new trucks for towing, but I'll stick with an 05/06 6.0, hate the interiors of the last GM trucks, but the Fords overall drive so much tighter and feel so much more solid. Fords got a new diesel being built in house to replace the 6.4, code name Scorpion or something like that I heard?

Matt's comments are similar to your own. He said the 6.0 engine itself wasn't terrible, it was just the electronics. He says the 6.4 is screwed up both ways. Time will tell.

Yeh the motors are good (6.0), and I know most of ours have tunes by SCT and run so much better then stock.
6.0 is a huge flop of a motor period. No mater what you do one of the cylenders will always run to lean because of a design flaw and the reason international lost the contract with ford currently in litigation. The 6.4 runs very strong and they just released a dpf delete tune that made 500 and 1100 at the wheels on the stock filter and exhaust. Say what you want but no duramax or cummins will run low 13's with just a tune or 1200.00 dollars. One truck has a little more aggressive tune that runs high 12's loaded crewcab by the way.

Didn't all 3 (Ford/GM/Dodge) say and tempering with the egr stuff, particle filter = automatic voided warrenty? , with normal mods (tuner,intake,exhaust etc) you won't have issue with that but they were pretty specific on egr/filter system, any thoughts?

I will take a Cummins or a Duramax any day of the week, year, or century for building a badass engine. You can run boost/power levels for 300k miles on a stock Cummins that would shoot a built 6.4's rods out of the block in 100 feet. It is pretty easy to chip a Cummins to 500 RWHP. I would be surprised if it didn't run 12s with the new tranny. It weighs a lot less than the Ford.
Stock Duramax's will make way over 500 RWHP on stock turbo and injectors. They aren't as good built for towing (banks likes em for drag racing though).
To get a cummins in the 12's you will spend 5000 on a trans right of the bat, need two boxes stackd to fool the computer, and a bigger turbo etc, around 8000 and up. The cummins is a great motor for pulling and as far as towing and gas mil. and is it is the king. Remember the cummins is its only strond trait. The rest of the truck is good old dodge junk and anything over 70 horse chip will blow the converter. Also the cummins does not turn as high rpm's. All Iam saying is that a programmer and a dpf delete pipe and low 13's to high 12's has put ford to be competitive with the duramax. As far as warranty turn off the program and replace the dpf delete pipe (a couple bolts) with the stock one and its back to normal. They are just starting to crack some of the codes and one of the ford engineers said they had to lstart from scratch because the 6.0 was such a different motor. And be honest, riding in a dodge in like being smotherd in cheap plastic, I would take a gmc or ford any day just because i like to be comfortable in my daily driver lol. But without a doubt the cummins is a great motor and my buddy has one in his convertible offshore boat and it really is low maintenance.

So they can tune now to stop regen? Getting rid of that stuff and running open with new exhaust etc, how was gas mileage?
Oh and it takes around 700 horsepower to get a cummins into the twelves and they cant compete with the duramax rev range, but I'm with you in the fact that if the two trucks attach a tow strap the chevy will get dragged down the street.
yep. Truck never goes in regen and actually blows a little smoke. My good friends truck is getting 2-3 better just as long as he keeps his foot out of it. If your interested check out powerstroke .org. There is alot of info and and search spartan and innovative diesel. The emmisions stuff actually hurts the gas mpg. One truck had some 80 hp injectors and a prpototype tune and hit 685 and close to 1300 and they have not even come close to unlocking the potential yet. I just thought it was impressive to have a daily driven loaded crew cab that will smoke just about anything up to 70 on the street launching in 4 wheel drive with the truck you tow with.

Cool, I've browsed that site before, yeh that emissions and regen crap sucks, all 3 suck for mileage now.

Cummins will win in pulling, dyno competitions, and drag racing hands down. Just take a look at the history of events. Cummins is almost always on top. The inline 6 simply produces massive amounts of torque. Funny that a 6 continues to stomp all the v8's.

Yes as far as all out built cummins 12 valve nothing can touch it yet but bolt on cummins are dogs compared to the duramax and new 6.4 and most cummins are dyno queens. They do not turn enough rpm and have to be fairly built to run fast. spend 2-5000 on all threetrucks and I garuntee the new 6.4 willcome on top. 1200 will get you low 13's and unlocking the codes has just begun. You also have to think how long the cummins has been around, of course it has an aftermarket kind of like the mustang 5.0
get dragged down the street.
