I'm running the edge on level 3, it will let me adjust the rev limiter, tire size,and the speed governor.

When I try to use some of the other custom options such as timing and wot shiftpoints,wot fuel etc...etc.. My truck for lack of a better term goes kinda haywire will acclerate Hard to about 3500 rpm but will not pull after that just seems to lose power .

I can return to stock and then reprogram level 3 with minor changes as listed above , and the truck runs great again .
04 Larait screw with 5.4

Any help would be greatly appreciated

 

Mine and others do the same thing! I tried going back to stock and updating and that didn't work too.
