im working on a 2008 6.4. i have installed the delete kit with live wire tuner, works great except when pulling a trailor. the throttle position is way to sensative, its starts jerking you around, you either let out of it or mash it to the floor to get it to stop and then you have to run the cruise control. i got everything from doug at ford specialists out of georgia. he has sent me 3 different tunes and none of them has helped. does anybody have any suggestions where to go for help/. thanks,mike in iowa

 

If you're running a SCT LiveWire, you need Eric's @ Innovative Diesel Performance tunes period; his Tow tune with softer than stock shifting rocks in my experience. Check my signature for a link... Good luck!
