I'm glad you were pleased. I still get that 'GRIN' I warned you about every time I hook to my 5er! As others have stated, please keep up on the service. Oil at 5k and fuel filters at 10k. There are videos on Youtube on how to change them yourself(if you are into that)and lots of write-ups with pics on the Ford-trucks.com website. If your truck goes into regen mode, try not to shut it down while it's still in it. If you do that several times, you will notice it starting to 'grow oil'. I suggest monitoring your engine and tranny temps as well. I use the Edge CTS #83830 for mine. It is not a programmer, just keeps you informed with real time data on your 6.4L. These engines love to be worked hard. The harder you work it, the better it will perform and the grin will only get wider!

Point is, modern V8 diesels don't run at higher RPM's to reach peak HP and Torque than a Cummins.
If you look at the torque curves, the 6.7 Ford has a much flatter torque curve over a wider RPM range than the 800lb Cummins.

If you have glasses, you should clean them. If you don't maybe you need some . It clearly says 800tq @ 1500 RPM for the Cummins, and 800tq @ 1600 RPM for the Ford. In any case, 100 RPM isn't much of a difference.


No glasses needed, your source and my source show a 100RPM difference for peak peak torque. My Source says peak torque is the same RPM, yours says the Ford is 100RPM higher.
Cummins requires more RPM to reach peak HP.
My post referred to this statement,"As far as RPM, the newer diesels like to rev more than the older ones, especially the newer V8s (as opposed to a Cummins straight 6)."
That is just not true for the Ford 6.7.Max torque is reached either at the same RPM or 100RPM higher for the Ford depending upon the source, and the Ford gets max HP at a lower RPM than the Cummins.
Therefore, the statement that newer V8's like to rev higher than the Cummins doesn't hold water.

Maybe that thought process comes from the fact that the V8 diesels make more hp (generally speaking) at higher RPM than the inline 6 does. Speaking from experience driving both, my Cummins is ready for the next gear when my buddies Duramax just starts to pull hard. Also I noticed when I pulled the same RV with both trucks back to back is that the Duramax wanted to downshift more/easier where the Cummins turbo just spooled up and climbed the hill in top gear.

We really don't need to "argue" the point anyway, the magazines (and e-magazines) have tested them all and the results are plain for everyone to see. The V8 (higher hp at high RPM) diesels will win that type of competition/test every time as they are testing with the foot to the floor. The margins are, for the most part, almost insignificant. Though, when there is a winner crowned in performance, the Duramax has proven itself the power king 90% of the time.

Here are some links to the torque and HP curves.
The Cummins is clearly the highest reving engine.
The Ford has the lowest RPM for both HP and torque,not by much, but still lower.
The Duramax gets its torque at the same RPM as the Cummins and makes max HP a little lower than the Cummins.
The point being is that it is a myth that late model V8 diesels rev higher and get their HP and torque at higher RPMs than the Cummins 6.7.
Also look at what Cummins did to the torque curve of 800lb torque upgrade.

Anaro, I had the same questions that you are having. I purchased an Edge Insight. It plugs into your OBDII port and can be mounted like a GPS in your windshield. You can monitor up to 29 different parameters and set an alarm to sound once you go too high in that parameter. Most diesel trucks don't come with an EGT (exhaust gas temp) probe, but yours does. The top line model Edge Insight CTS can also be used as a back up camera, which comes in very handy when hooking up by yourself.

If you have any questions feel free to PM me.

I got mine from Thmotorsports.com for $319

There are lesser models that aren't as pretty to look at, but serve the same functions. Just look up Edge Insight


These are the numbers I've been given for my Duramax.

No more than 1350 degrees for short bursts on EGT's

No more than 35psi boost for short bursts.

As previously stated, your truck won't let you hurt it unless you have it tuned to ignore stock parameters. Welcome to the world to diesels.

This is what the Edge Insight CTS looks like installed(in a 6.4L F350) with an optional mount and painted to match the interior.

Well thats to bad, but it doesn't change what I said.
The torque curve on the 800lb tune is ugly for the Cummins. It looks like you would be better off with the older tune.
With the H.O. tune max torque is still at 15-1600RPM, but then the torque starts to rapidly fall as it reaches max HP at a little over 3kRPM.At max HP torque has dropped to about 630lbs, while the Ford reaches max torque at about 15-1600RPM and and the torque stays the same all the way until mas HP is reached at 2800RPM, which is 800lbs.

What does this have to do with the questions the OP has asked? My tuned Duramax will spank both of you, but you know what, NO ONE CARES!

It's sad what happend to the Cummins torque curve. It used to look like a butcher block or pool table from idle to you hit the gov.

Now it looks like some of the hills I tow up......and down.

I'm hoping urea will solve that issue.
