6.4L Upgrades and Aftermarket - EngineUpgrading and adding aftermarket equipment to your 2008 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.
I installed the SCT Livewire last night, and I could not believe the power that has been added. I have only loaded the extreme flash, so far. It is so suprisingly fast.
The reason I bought it is to increase the MPG's, so thats the important thing to me. I will let everybody know what I get. Right now if I drive like I like to, which is about 75 on the highway, I get around 12.5 - 12.9. If I drive to conserve fuel (which I hate), I get about 14 mpg, and I have to take off easy, and I dont exceed 63 mph on the highway. I have 90 miles of highway travel everyday to work. I will let everybody know what happens. I hope for the best.
If you drive it normal and only use the power when you need it, you won't have any more regens than stock. If you are heavy on the pedal, you'll have more frequent regens. It won't hurt anything, but your mileage will suffer.

Did you have to play with transmission setpoints? Or did you just download this setting right out of the box. I am still debating on getting one, but I didn't want to screw with defueling, tranny settings, etc.. I just want to download one thing and be done with it.

Do you recommend putting it on "Performance" instead of "Extreme" ?
hey i love your upgrade man, that is SCT Livewire is slick. just be careful with it as much as possible, maximizing its use might have bad effects on the car.
I put one in and just on the performance mode if you get on it hard it dosen't want to shift right. Any suggestions?

I put my tuner on "performance" the first week. I got pretty close to the exact mileage I was getting before. I stayed below 65 except maybe twice. I also got on it to pass someone on the highway twice. I'm kinda dissapointed. I love the power, but the only reason I bought it, was for the increased MPG.
I am trying it on the "extreme" setting this week. It's seems to be getting better so far on the "MPG meter". I'll let everyone know at the end of the week.
Linear Mode
