Im guessing you have 3.42s? or reving it pretty high with 3.73s?

Mine shifts 2-3rd at 91mph, 6000rpms 29" tires.

On my first 1/4 mile run it shifted to 3rd early and killed my times, so then i just dropped it to 2nd and ran the rpms up. trapped at 91.65, so i just upped the rev limiter and shifts at 92-93.

 

Mine shifts out of second at 99mph.3.42 Gears and rev to 6700rpms.

 

you got that truck running strong blue!
keep up the good work

 

Damn Joel, that thing pulls strong You should have come out to the track Friday night, the weather was ideal.
