6.4L Upgrades and Aftermarket - EngineUpgrading or adding OEM or aftermarket equipment to your 2008-Up Super Duty truck with 6.4L Power Stroke diesel engine. Please confine discussion of topics in this forum to those items that are specific to the 6.4L Power Stroke engine.
Ok; I have been thinking (I know it is a dangerious thing to do) but how about a detuned chip insetad of uping the horsepower and torque drop it down a ways for fuel economy when empty and then a posistion for stock. For what I tow I could get away with 300 horses and 400 pound foot of torque most of the time.
So would this give you better millage or worse, and how about the overall driveablity of the truck. I know that they uped the horsepower to help out the DPF and the regeneration but I was just wondering.
Mabe I am getting old these days but I don't need to beat the ricer that is sitting next to me to the next light while I am loaded. Perhaps the next guy does but I don't. I agree that it would be suprising to see just what these new engines would put out without all the crap that is stuck on them but I don't believe that I need it all. In most cases my 7.3 does all that I ask of it and more but I am almost to the point of needing a newer truck with extra room. So I was just wondering if you detuned the 6.4 down a ways would you get better fuel ecomomy empty or with a slight load? Perhaps you could get into the 20's empty. Just food for thought.
When I turned up the wick in my Dodge it was 423rwhp and 950+lbs/ft of torque. I remember one poor family at the light next to me when I was pulling about 21,000lbs. The last I saw of them they were in a cloud of black smoke. I felt bad and was laughing at the same time. The torque in the Ford will never match the in-line 6 Cummins.

You already have that. All you need to do is not press the go pedal as far. A chip the prevents the engine from making max torque is only going to make a difference when you have the pedal on the floor. It will act like you are only part way down. Just make that change with your foot and you don't have to buy anything.
I see the bigger market for a de-tuning programmer being fleet trucks.
If I wanted longevity and less fleet fuel costs and I owned a dozen F250/350/450/550 trucks with 6.4 I'd get programmers in an instant to ratchet down the the power.
There is difference between lesser pedal and good programming that detunes the engine. You can have timing changes that up MPG without extra fueling or even with reduced fueling. You can have close to the full torque at 2000 RPM but not let HP go as high at higher revs.
Look at the power/torque specs on DT466, ISB 5.9, etc in medium duties. There are a number of HIGH TQ low HP versions there.

An excellent fuel economy mod is a ping pong ball that lies on the carpet under the go pedal.
In a dire emergency, you can romp on it, crush the ball and go...
