Anyone peg their 6.7l yet?? Prior to 25k miles, my truck seemed to hold @ 90 m.p.h. forever like it was running out of engine to get past that speed. Just over 25k I tried again. I don't really do it that often, but this time as soon as it got over 90 m.p.h. it just zipped up over 105 m.p.h. so fast it took me by surprise!! Now it can get up to that speed fairly easy each time I try. My 04.5 with the same gears got up to 100 m.p.h. pretty quick but I think the 07's gonna be a bit quicker when it loosens up. BTW I use the same "safe" stretch of highway to do my "testing"
